If you bought top altcoins or good altcoins that has a potential in the market last March and April you are 30 to 50 % profit, now that we are in the bull period, what coins did you bought when the market is in the bear period.
certainly a coin that has a large volume and a clear concept, and has good teamwork to develop the project. the coin is in the top 10 marketplace, can't doubt it. I think investing in coins that are in the top 10 marketplace is safer.
