I have gained money with a lot of coins. However, the coins I have gained money with include:

BNB: I mean, this gave me an x40 return and that's because I didn't get in at the earlier stages. BNB might have made me  a lot of money in the past, but that is not the end. with binance coin being the native currency of binancechain, I see BNB hitting 100$+ in the future

COUNTINGHOUSE TOKEN: Actually I got 3500 of CHT during their bounty. they are a hedge fund that use a special kind of algorithm to remain profitable. the price was just around 0.5$ when i got the bounty, but now, the price hovers around 3$

ONTOLOGY: got into their airdrop. as at that time, the value of my airdrop was 900$. but ontology saw an x10 growth and sent the airdrop level to almost 10,000$. Ontology is still a great buy now.

ethereum: bought ethereum at 0.8$, sold at 720$. hence, that made me quite a lot.
