I think it is better to continue investing in more potential coins. I suggest to invest in altcoins, not in bitcoin. In my view, altcoins has a higher chance to have bigger profits. The price movement can be easier to increase significantly. But you must be very careful and more selective yet many altcoins easily become useless coins after listed on exchanges. The best way is to choose top altcoins, for example: top 15 altcoins in coinmarketcap, and avoid to invest in ICO coins (if you are not sure it is a potential coin).
