if in 2019 will begin a fast rise in the price of bitcoin, then most likely I will sell bitcoin when it reaches 25-30 thousand and then wait for 10 thousand to buy it again
Speaking of rising of the price, it seems that there is no fast rise of price simply because until the price is still around $3000-$3500. The thing that I will do in this year 2019 I will trade different altcoin which can also brings good income.
