It all depends on what kind of risk you are willing to take and what kind of profitability you expect. But we need to take into account the realities of the market. First, the market is now falling and it is unknown when it will grow. That is, you need to count on a period of 2 to 5 years. Secondly, most of the ICOs ceased to show good profitability. Immediately after listing on the exchange, many tokens are very seriously losing in value.
