I'm not sure myself which way to go is the best. By the way, I don't even know what is 'CSV' and what it entails for the coin's future - if you could explain in a few words.
CheckSequenceVerify (CSV).
CSV allows users to block selected bitcoins for a specific period of time, resulting in that after this period the coins will be unlocked for transactions. The main difference of CSV protocol from another solution, called CheckLockTimeVerify (CLTV), is that the latter locks coins until a specified moment in time while CSV lock is relative and applies only after the transaction is included in a block. Thus, CSV implementation will provide greater flexibility in transactions and ability to create more advanced smart contracts etc.
It is set to improve the Bitcoin protocol. For example-a long-awaited fix of transaction malleability.CSV lock is relative and applies only after the transaction is included in a block.As a result CSV implementation gives more flexibility in transactions.
This is useful for Payment Channels which are great for micropayments or for fast payments.
