this proves that all that is needed is patience. if you hold a few coins before 2020, you have benefited from it. for examples like bitcoin, ethereum, LTC, XRP, BCH, BHC SV, and many more, don't you just have to hold back a little longer to make a profit from it? Well, information is important, but I think this year has good information to hold assets.
There are several ways to profits from the market, what you are proposing seems similar to fundamental investing and it is a way to make money in the markets, for example ethereum is almost 90% away from its ATH, we know it is a good coin and that it will eventually recover so if you are a fundamental investor it makes sense to invest in it now and if you are willing to wait a few years I have no doubt a person with that strategy could easily double or even triple his money.
