If you are not able to MN things or shared MN, you can stake your coin by your wallet too. That is an option like that as most of us know.

Proof of stake wallets allow 401K uses to earn rewards by holding any amount
of coins in their wallet. There is no need for a locked collateral amount. Proof
of stake rewards are distributed by network weight. A holders network weight
is defined by how many coins they have. If a holder has more coins, the
likelihood they will be able to hit a reward is higher than a different holder who
has less coins. A simple way to look at proof of stake rewards would be to
consider every coin in a wallet as a lottery ticket. The more tickets you have, the
more chances you have to win that block reward. The proof of stake rewards
are 25% of the block reward. If the block reward is 10, the proof of stake wallet
reward is 2.5.
