As per the current market situation, many good coins are falling due to dot, cake and many other reasons. I would suggest buy cake, sol, and such coins for at least 5k amount, and soon those coins will return high profit margin
I think we absolutely will have high profit if we have already invest to SOL in July, because the price increased 600% in the mid of this month. And I still believe that SOL will give us much profit in the future. Also i wanna suggest to invest to ETH, I think it is a good time because eth price has correction and we will get more profit when the price is up again.
