..............if you do it like the EARLY btc and eth investors. But going in eth and btc now is risky because you wont make $1m out of $1000.
If you want to make $1m out of $1000 you better go in promising NEW projects that are still cheap like koinos which can still go x1000
I definitely agree with your first sentence here. BTC and ETH already made their first investors rich and by rich i mean literally from 100$ to a million. That was definitely possible if you were a very early bitcoin investor and you managed to hold your BTC for a few years. Even with ETH it was possible to make a x3000 of your initial investment if you were one of the very early investors.
The big problem is that nowadays there are so many new projects coming up that it is very hard to find one that is really promising and that will have an impact. So to find a project where you can make a x100 is still possible but very hard in my opinion. I think that 9 out of 10 new projects that are appearing will be gone again after a few months.
