Aside from that, if you want to earn passive income in crypto, I can recommend to stake your tokens but this not a guarantee that you will be profitable because even though you will get more tokens the price might decrease. So you have think it every well before you decide.
Betting on Bitcoin is certainly a good idea, you will receive 2 benefits at once, namely from the long-term investment of Bitcoin that continues to rise and the profit from staking done by seeing how much you stake.
This can be done only on centralized exchanges or some crypto wallets that support staking.
Regarding risk, it will definitely be the user's risk, and must be aware that each platform has its own risks.
It is better to stake on a supported wallet than on a centralized exchange.
Passive income will be earned and more tokens will be owned when staking runs long enough (depending on the APR given).
