I only know that the primary consideration is to choose tokens with potential, but here's the question: besides Bitcoin and Ethereum, what other options do I have? These two tokens are quite a financial burden for me. Also, can the interest generated from staking all tokens be traded?
If you are staking, it means your tokens are on the centralized exchanges. I know some wallets support staking as well. But, I don't think any Bitcoin wallets support staking. It is recommended to move your funds to a non custodial wallet. I don't know what others may suggest besides Bitcoin and ETH. but I guess TON has a bright future because of Telegram.
Ton has many use case right now since telegram started allowing developing mini apps. Crypto airdrop projects are now adopting TON. So, I see a very bright future of TON at this moment. Probably there are some other options, but I will stick with TON.
