My strategy is to avoid risk! I do that by not day trading. I invest my money into several coins and I wait a few years to see what happens. This is the best thing with the tiniest risk. And make sure you only invest capital you are ready to lose.
Invest in bitcoin is not risk. Always think a positive that your money you invest will gain. If you that price getting down dont make bet just save it in your wallet, but if the price will get high like a rocket invest the amount you want it. It is your decision how play a game in bitcoin.
