For me, that had to be Ripple. I traded for 100%+ thrice and still holding a position at $0.40.
My next coins are:
1) Ripple
2) ADA
3) Bitcoin
4) Ethereum
What's yours?
of the four coins you offer I have made a lot of profit from bitcoin and ethereum, a few years ago when the price was still cheap I bought these two coins BTC and ETH, I tried to save it and a few months later the price became very expensive and I made a profit withdrawal with a very large number, in cryptocurrency all can get a lot of profit.
