It is better to make long-term investments in cryptocurrencies; However, at the moment the price of Bitcoin is very high, which has increased by almost 100% in the last one month and is above $40K, so I think investing in Bitcoin is very risky at the moment. In this situation one should wait or short trade without investing in Bitcoin in the long run. Although the prices of other top coins have gone up a bit, I think they still have a long-term investment opportunity.
