Doing your own research is clearly the best way to do it, as well as to hone yourself so that what we are going to do is in accordance with whatever we have researched before. because every thing we have done with care alone is likely to be wrong in the end when it has placed the funds, but it will certainly make us more careful next time. if you really don't want to do research and look for safety, of course using the highest rating in CMC is definitely the best course of action, because it's true that in the current situation which is still in a bear market, it is very difficult to determine exactly. but indeed buying and holding it is highly recommended at this time, because it will still take a long time for a bull market to occur which is sure to happen.
