Hi all!

I'm new to investing overseas and I'm planning to buy ETF. I've read a little to realise the following:
1. IBKR is cheapest but need maintainance (or some minimum amt of money which i dont have)
2. TDAmeritrade is fine, but they recently move MY clients to SG, flat $10.65 per trade. Not expensive but not optimized.
3. IBKR whitelabels (tradestation international... etc)


I'm exploring option (3), but I am worried that they might.. go vanish, and in this case my $$ and stocks will be liquidated? I cant find reliable review online. Any help?

that's true, just slightly annoyed that i'll need to pay for buy & hold strategy.
