Absolutely. Don't worry, Bit-X will prove their legitimacy plain and simple.
I wont surprise if CloudMining.website claims the same. After all they are paying longer than Bit-X.
Any reason why you stopped promoting the cloudmining ponzi? (I applaud you actually).
'Paying longer' is no proof. If a company has been paying for a month it can still be more legitimate than a company that has been paying for a year (yet is run by investors' funds, a ponzi).
Bit-X will be able to prove much further than just "paying out since 20xx". Already, it's the confirmation from BitFury and soon much more.
