I agree, for some people investing in crypto, 7k is a modest number, but for those with difficult backgrounds, it is more than enough funds to start. There is no absolutely safe way to invest, but 7k based on a safe strategy, Bitcoin, ETH, BNB, SOL are a good choice. He can certainly consider entry entry options or apply DCA if necessary. It is possible that with many different ways and flexible portfolio combinations can bring higher profits.
