I think what's more important than the amount you invest is the time you invest. Buying at all time highs pretty much ensures no matter how much you invest, you're probably going to lose money. Investing at all time lows with very little capital makes much more sense than investing at all time highs with very large amounts of capital.
It is right that experience and skills are mandatory for making money from crypto investment. if you join bounty campaigns you must upgrade your level and find some authentic projects for earning money but it is not guaranteed until the ICO is not listed in exchange. It is also possible that you can make huge profit from new ICO after a couple of months.
