Free money for holding coins!

[AlfaStar95]

Hi!

I just found out that you can receive GAS for holding NEO, ~ 10 % / year for NEBLIO, and 1 IGNIS of every 2 NXT.
+ 4 % weekly for holding BTX.

The 4 % for holding BTX sounds too good for me. Who gives you the same %. It's insane.

What do you think about that.... Do you have trust in this or do you think it's too risky?

Also, do you know other coins that give you free coins / % for holding ?
