I did a 1000% (or a 10x for those who prefer) with Ethereum. That was kinda "the opportunity of my life", since now all the money I get descends from the one I got with Ethereum.
for those who invested in eth and monero when it was below $1 had a ten fold return , i wish i knew about crypto during that time,i feel that i am really late into this venture ,now the markets are saturated with enough coins and you never know which one to follow other than bitcoin
