Hey - looooong time lurker ..... longer time holder. Think this may be my first time posting.
Long time interested in earning interest. To date, all methods of doing that just seemed like a good way to lose whatever coin I elected to lend.
However, been looking at blockfi lately.
Anyone have any experience with it?
I do not. But I think it is worth considering the track records of trusted third parties holding the keys to "your" bitcoin, and how that makes it effectively their bitcoin, and exposes you to all the counterparty risk that brings with it.
BlockFi may be a perfectly good organization, as were/are some organizations this list (which is not complete):
