With high market cap coins as yours, the potential, the hype is already in the price. Why else do you think they are worth billions despite having often nothing but a whitepaper really? No real world products yet? They are hyped to the sky. Many people got millionaires, made tens of millions by getting into them cheap. So of course now you can still profit, but much lower. No way they go x50. Unless if bitcoin goes x50 to $750k a coin.

Do you see bitcoin at $750k anytime soon?

Same with people going into Verge now. I dont even know why to bother with this anymore, but if you look at the people who made x30, x50 and more. Its those who bought Verge, Raiblocks, Tron, Iota, ETH, Bitcoin when they were low.

So if you can think for yourself which you seem you CAN, you will come to the right conclusion I hope for you :-)

So this means you will need to buy $50m, $100m market cap coins as maybe Oyster Pearl and Zoin, Colx, Linda and others to be in the next Verge/Iota/Neo/ETH. You are simply too late on the coins you are buying.
