> - Raspberry Pi is way underpowered to run any SaaS on. Probably sufficient if it's written in Go or another compiled language. Obviously depends on how much revenue you're making per hit, but certainly within the realm of possibility. > - Bitcoin's network is too congested for it to be used for trivial payments such as subscriptions for SaaS. There are alternative coins that would work quite well, if fees/txn is the concern. Current fees seem to be about $1.15/txn, which is quite high if you're only charging $5-10. > - A bitcoin node takes hundreds of GB of storage itself. Bandwidth costs will probably be significant too. This means the SaaS would probably have a hard time getting to break-even. Few people run a full bitcoin node, so I think it would be sufficient for this use-case to send txns to the network via a third-party service. > - It may be more profitable to climb up the tree and steal the pi and then take its bitcoin private key Honestly the human factor involved in the whole scheme is probably the hardest thing to make happen. There's maintenance, h/w failure, the difficulty of finding trustworthy contractors who don't need human guidance, etc.
