Given the beginning of the Bitcoin bullrun, almost all coins are able to grow and bring good profits. At the same time, in my opinion, ONE and MATIC are the most promising altcoins. On June 30, these projects launch their mainnets, which should lead to their explosive growth.
There's no signs yet that altcoin is running with bitcoin, with that launch, I guess they are on timing and it maybe will not result to a pump that time but sooner investors will see that when altcoins in general will also rise like the way bitcoin is rising.
