You should take into consideration that projects with small cap could reach x100-x1000 growth pretty easily. So I'd like to recommend to look at recent ICOs. For example comsa made x3.5 in 2 weeks, cindicator made x7 in two months , stratis cost $0.01 during the ICO and take a look where it is now it made more than x1200 in just one year.
Why many people asking that kind of altcoin can grow 1000x in price. I know thats very huge profit if we find that coin but also more risk is involve in that kind of altcoin. I prefer to get lower profit with lower risk. But this is just opinion. People have different thought.
