Certain Crypto availability

Hey folks,

Does anyone know why certain crypto listed in trust wallet is available to buy and some are not? Meaning some have the option to buy right there when you click on them while others have no option to buy. I do not understand…I could use some clarification please and thank you.

Don’t know if I am wrong… But I think it has to do with demand.

Thanks @Mike2microbe, I just find it strange. Some of them like Theta is up 1.34% and I have researched this crypto and interested in getting some but no option to buy. Lol!

There are galore of options in exchanges…preferably Binance


I think they are not listed in binance dex and they are not bep2 products
