I would hold these Bitcoins for a while. Because in 2018, Bitcoin was the most stable coins and I would also buy some more altcoins, because I have the feeling that the pump is near and we will see the green market pretty soon.
I hold Bitcoin for a long time because the coin is building the price and the amount of coins in Crypto.
by having a number of Bitcoin it would be very good with using it as an investment. because of the growing capabilities through investment Bitcoin is able to generate more profits that made it so precious coins. so highly recommended for investment.
