We create smart contract for HODLing bitcoin for 5 years (that’s rough number, could be anything). For users who send their BTC to the smart contract, some new token or coin would be given. Tokens have their tokenomics, the whole thing is DAO with voting, stakings, farmings etc. For HODLers NFTs can be generated to create community thing.
This sounds to me like one more scam token is being made on some centralized shitcoin network with sole purpose of stealing Bitcoins from original owners and creating false sense of security.
If you want to make it harder for yourself to spend Bitcoin just make some multisig setup and spread it in multiple locations that you can't access so easy.
You can also split your keys from that multisig setup with some of your family members or friends, and create special terms for signing transactions and spending funds.
