Buying in ICO is kinda risky especially in some sus project out there but it's worth it if your lucky to get into a great project the profit is kinda good actually.

Buying coin and tokens before burn? I don't think so. Buying top volume coin? maybe low market price coin could actually give you a much higher profit than the coin that coin higher and needed a high investment.

It's a kinda simple, investment in a potential token in the market and then take profit every time the market is pumping and then hold when the price is dump or low.
