Thanks for all the replies. I am trying to do a bit more due diligence to verify the information on the website and other sources.  So far the information has been consistent....

It is interesting that most of its current customers prefer to be on a low-key mode and not willing to share the referral code public. Is it because the referral code is revealing certain client information or is it the policy of APYHarvest?
 
I think I am probably waiting till the end of this year to see its audited financial statements to be filed with the UK authorities before I make up my mind on this.  The way it conducts its business is quite interesting (with founders and everyone involved on a relative low-key or even stealth mode, in contrast to the founder of Celsius and others Crypto players).
