I own different crypto and mostly I stake with them because I am interested in the long return. With bitcoin I am actually doing nothing.
If you are primarily interested in the long return, then hodling bitcoin is your best bet and would potentially bring you more profit than staking assets which are built on the PoS model. Not to shot on proof of stake, but one of the main reasons bitcoin actually increases in value is due to the controlled and reducing supply and how no one holds more stake on the network.
Can you suggest any strategies to make even a little APR? I know that I can't stake with bitcoin.
There are third party services that you can technically stake your bitcoins with, but as a common rule; Not your keys,Not your coins.
