It'll take plenty of shamans and crystal balls to come up with that answer......
Seriously, though, many financial experts and analysts (except the naysayers) are recommending to hold, instead of sell.
We haven't seen the end of this bull run yet, I dare say.

Is there any particular reason you chose Bread Wallet compared to other wallets like, say, Blockchain.info?

Who knows......
Perhaps, like BitX, they gave sufficient notice to all their investors to either withdraw or transfer out their bitcoins before the website closed down.
But, technically speaking, if they didn't alert anyone and just suddenly closed down one fine day, I suspect all the funds would then be lost to the investors, and into the company owner's pockets, because they are the ones holding the private keys for the investors.
Letting an exchange site have control over your private keys is something akin to giving your physical wallet and cash to some stranger on the street, and basically just hoping that he'll still be there the next day and not run off with your money.

With so many large scale miners worldwide, especially in China and northern Europe, I'm not sure individual mining is really a profitable endeavor anymore these days.

Well, initially mining was good business, but the beauty of the bitcoin technology is that it is self-regulating, so as more and more miners jumped on the bandwagon, with increasingly better, faster and more sophisticated hardware, causing the collective computing power of the blockchain to increase tremendously, the algorithm has adjusted itself to be exponentially more complex to solve, meaning you'd need really serious hardware.
Now, if you want to compete with these high tech miners, you'd need very expensive hardware (think tens of thousands of RM) running 24/7 just to have a serious chance to compete, and most likely, the returns you get is not even worth all the electricity bills you'd be paying throughout the year.
Now the competition is even more intense after the halving that happened this year.
It's not impossible, but think very carefully before you decide to go down this path.

Otherwise, the "easier" path to take is the trading or investing path, i.e. buy and sell.

To be honest, I don't personally anyone who is doing mining, so please do let us know your experience after you have tried mining.
I'm quite interested to know actually.

Yup, you're right!
They're called ASICs (Application-Specific Integrated Circuits).
These days, I hear that you won't even earn enough from mining to cover the electricity costs.

A good time to invest in BTC would have been back in 2009 when it was merely cents each.
It's risen by more than 100% in 2016 alone.
We're starting to see the beginning of a bull run now, so personally, I'd say yes, now would be a good time to get some bitcoins.
This is just my personal opinion, and is not a recommendation to buy or sell.

Wah......every week can buy RM20k of BTC......you are damn rich......

On the contrary, I look at the dips as a major discount to accumulate even more.

Since the price has broken through the psychological barrier of USD 1000, and inching near the all-time high, a lot of traders are starting to cash out their profits.
A price correction like this is inevitable, and in fact I see it as a good thing.
Small and frequent corrections will help to stabilise the volatility, and prevent huge catastrophic crashes like the one in 2013.

How have your returns been so far, since June 2016?
Mind to share?

Oh, I mean in terms of bitcoins, how many bitcoins can you actually earn from mining?
E.g. approximately 0.01 bitcoins since the last 6 months, etc.

Cool, thanks for sharing.
That gives a rough idea of the returns of mining.

Indeed.
Though, I admit I am more of a "hodler" than a trader......so far I've only been buying, not selling (especially since the dip now).
I have high hopes for BTC!

Which is why I never do trading, either for my funds, stocks or now bitcoins.
I'm too lazy for that.

Yeah, me too.
But I am holding out for the longer term now, unless I definitely need the money.

How I wish I have some spare cash right now......

Very sorry to hear that.
Did you call the number back to check what is the problem?
But, since you have the name and account number, please do not just let it go.
Get ready all the written correspondence with this individual, and quickly lodge a police report and contact Maybank and also BNM to raise an alert for this issue, as this is clearly a case of criminal fraud.
Scammers thrive on the bet that the victims will not bother to take any action, in which case they will be emboldened to continue their criminal acts.

20 BTC at USD200...! Damn...lucky you!
