If we started by accepting this risk, there is not another choice but to choose the best one. The current situation is also good to collect from cheap price for future. Get it, and just wait, you will make good profits.
the best solution for now, is to invest indeed by choosing the best coins, although it is difficult to find the best, by looking at coinmarketcap as references we can see from the top coins that have a high market capitalization, they will be able to continue to survive and grow in the future.
so the risk that we face is not too big than choosing a coin that is still unclear in the future.
