Bitcoin staking can be another holding/investment strategy for idle coins or upcoming traders. It can be done in two ways. Flexible and fixed. The flexible staking is one that can be unstaked at any time. While the fixed is staked for a shorter period but must be redeemed for it to be unstaked. This means that in flexible as the word implies, it is not rigid and you can terminate the staking any time you want but fixed is a rigid one that cannot be terminated and must reach the timeline of the staking. The rewards in staking is earnings. For freshers and even professional traders, staking appears to be a very viable investment opportunity for profits. The fixed staking has higher APR while and cannot be unstaked until the maturity/redemption time. While the APR for flexible is lower and can be terminated at any time.
Staking and earning is good for idle funds/coins and can really help upcoming traders that are always busy with other works or activities.
What do you think about this?
Reading your post I assume that you are talking about staking on exchanges because bitcoin by protocol doesn't provide staking facility.
If you are allowing 3rd parties to stake your bitcoins then you are going against the bitcoin protocol itself.
If you don't hold the private key to your coins then you don't hold any bitcoins.
That said, your idea of staking bitcoin is not something any true bitcoin supporter would encourage.
