Actually want to ask, how do people play buy low sell high? Example buy 1 btc in early days:

Bought at 190K
Sold at 230K
Profit 40K

Then see the market strong, buy at 240K (190K+40K=230K). End up top up +10K to enter back into crypto market.

Hence do buy low sell high only work for short term, and not long term? and a lot of people say after sell, wait until the price drop. But what if it doesn't drop? Like now, we don't see 190K btc (which is just few months back). Open for discussion
