I sold my 6k ripple coins last night! 
Sell at low price? HODL you will regret, yeah, I hold minexcoin and regret not sell when it is 30 USD. now it is 5 USD. Sell the coin at the highest price you will make profit. If not you will regret, crypto price is difficult to recover from the red bloody dump. Yeah, even from 5 to 10 USD it is very difficult. so sell your coins when you made profit. never hodl for long time, you are dreaming by hodlchange our plan as being emotional in trading and investing will most likely result to a disaster in the long run.
I learn from my mistakes last year, I will sell now when bitcoin reach its ATH.
