Best option is to buy bitcoin while its cheap hold it for a number of years and wait for prices to go back up. Got into BTC when it was at $13  a coin wish I had bought more than I  actually did then  and waited for 2013 and sold. Shame only bought like 60 to 80 of them and in time bought more sold more and exchanged. Should of just bought a tun of it when nice and cheap and enjoyed the return on it from going up so much.
