Maybe they are trying to get enough BTS X on their exchange so they can have much power to vote for delegates???
Don't centralize BTSX...keep them on BTSX official wallet and trade them for Bitusd or else prepare yourselves for manipulations...
The 1% bonus is something they do for all coins deposits.
And they take it back on withdrawals.
But centralized exchanges voting power is something that concerns me too...
It reminds me the paradigm of multipools on the bitcoin ecosystem
PS I hope the majority of investors will keep the funds on their personal wallets...
except of security reasons will they have other motives to keep them there? (dividends/shares?)
