Of course, investing in cryptocurrencies is profitable, but you need to choose the right time for this, choose good cryptocurrencies and have a clear strategy. If you invest simply without these at least three factors, then there is a high probability of losing your funds. If we talk about investing in cryptocurrencies right now, I think now is a good time for this, since there is a high probability that by the end of 2021 there will be another growth phase. All that remains is to choose the right cryptocurrencies for investment and have your own strategy for holding down and then selling purchased cryptocurrencies.
