Generally, the whole of Polkadot ecosystem is still in its infant. This will be like investing in Ethereum at 200$.
Sooner or later when polkadot is being adapted by many it will be good, we can see the competition in our chains between bsc, eth and polka, i don't know what polka can offer to us in terms of transaction fees and speed i just hope that it will create more news so that they could establish their chain so we can see the competition, by doing this I am very sure we will no longer experience congestion and hugh transfer fee.
