hi guys. can you help me that I have known nothing about blood wash term:-\
I have got some BTC that I bought when its 11.5k USD. should I keep BTC and hold or buy some altcoins?
You still have to hold the Bitcoin you have and you have to buy some Altcoin whose prospects are also good in the future. You must be smart choosing a promising and profitable Altcoin for you. My advice maybe you should buy Ethereum, but I am not forced.
