The talk here was usually that loaners were hurting the price or something for very little gains, so I didn't look any further.
The rates are at 0.15% now should there be another breakout it could see 0.49% again which is more than 3 times the current.
The ones who told you that are probably the ones loaning themselves.
The advice was against lending at an extremely low rate. At that time there were many coins available at under 0.1%. Sometimes even bellow 0.02%.
