No. I think zaps stay small bit the number of participants grows and it balances out. 1 btc = 1 btc. Stacker is helping to set the value of things in Bitcoin. I like the fact that they have set prices and plan to keep them.

I don't worry about it but I might have to rethink my strategy if/when that happens.
