I don't think there's something that needs to be done to make bitcoin stable as far as its market value is concerned. Let's not forget that bitcoin is a very volatile asset that relies on the supply and demand.
It is good to hold your coins for long time but if there is no circulation of cryptos in the market, trader will not be able to make money, because there will be no buyers and sellers in the market. I think that the best idea is to use your coins in the markets for shopping instead of holding in your wallet. By this way the price will never down and hope will increase gradually.
