There are aspects that make bitcoin users more and more convinced that bitcoin is a good place for investment so now bitcoin prices are rising in the market!
Bitcoin's price is going strong, but not as strong as the alts in the market. Altcoins' price are shooting through the roof. It doesn't matter which alt you pick. Most of them have given phenomenal gains in the last 2 months.
I think that the price of any increase is due to the number of users is growing rapidly.
