the #1 problem with bitcoin is basically nobody spends it.
BTC is decerntralized cryptocurrency. But 1% of the population holds 99% of the money. It is not fair for 99% of population who have to pay the equivalent amount of fiat for BTC at the exchange. It is the 1% of population who is a member of the co-founder or grab extensive mining rigs. They will scoop great profit from the holding of BTC unfairly.
