#Bitcoin is definitely not a payment processor. While it was used a lot for tipping several years ago, it's not suitable for it due to scalability reasons. That's the Bitcoin blockchain, though. It's feasible to make small Bitcoin payments through the #LightningNetwork. It's a payment network built on top of the Bitcoin blockchain and has good scaling properties.
I wouldn't call it a pop investment scheme, but I acknowledge it's not ready for primetime use yet.
