Local investment experts will advise you to invest in top 10 cryptocurrencies. But I think this is extremely wrong. You need to look for the most promising projects and invest in them, rather than follow public opinion and act like everyone else. Moreover, it will not be possible to make 10x on cryptocurrencies from the top 10 list in the near future, since they are growing very slowly in price and there is no such idea behind them that would allow to increase investments in such a volume.
