you think this is the right time to buy and hold bitcoins? because from 19k its 11k today. 
Yea now right time to buying btc cause today btc price is many low. If you want to buying btc you don't follow btc. I think day by day it price increase. If you today don't buy after a day it price can be 20k + it is not miracle. I hope it price highly increase after a time. so you buy now.
