Tokens will stay locked untill everyone has their tokens and passed the KYC process. This is so some buyers dont have some sort of advantage like selling their tokens while other people cant even move theirs.
Unlocking of all tokens will happen at the same time no matter when or how you bought them and when you passed KYC.

You have 2 ways to make profit the weekly mining income and price of token. Its a smart move to keep the tokens untill mining has started and is going on for a couple of months.
More hardware will be online meaning I see the weekly payout rising not decreasing over time.
Depending on that weekly payout the prices for tokens could skyrocket. So I am planning on holding my tokens untill the project is up and running for a good while.
