For let's say x100 I think you might want to look at the altcoins that go under 0.10 USD right now. Wouldn't be surprised if coins like this would pull off easy x100 when the next bull market arrives. ADA, ZIL, HOLO have good chances to really make a strong jump.
I do not think these coins can increase, and I always hold BTC or ETH, because when the market rises, the ETH and BTC coins are the first to rise. And once ETH and BTC rise, the other coin increases.
