@OP, I think your should make an adjustment to the topic, because not all early entry always wins or gain this kind of profits. There are even too many bad profits that caused investor losses than the ones that actually generated profits for them. What I think is right to say is that early entry into a good project can make you win. Despite that I invest in most of these altcoins, I am very careful with them too because I have the knowledge that altcoin investment is almost similar to gambling, lucky if you meet the right project early but bad luck if you meet the bad project early too.
