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?
I was holding and accumulating Eth from last cycle because i believed in it and still supporting it but recently i did took some profit for everyday needs by cashing out but still im holding large amount because i know eth still has great room to grow in price.
