Next to the other arguments, the colocation is pretty cheap. In Germany, you can calculate ~20ct per Wattmonth for electricity, so ~1€ of this would go to electricity alone. Hosting at home also tends to come without static IP and non-symmetrical, somewhat unstable connections (speaking from painful experience).

For this service you pay ~6€ per month (assuming 50€ for the Pi and two years of runtime, no SSD) for a rather powerful VM. Just as a comparison, at Linode, you get 1 shared CPU and 1G of RAM for roughly the same price, compared to 4 core and 4-8 gigs with the Pi. Storage is even more expensive, so if you attach a large SSD, the calculation becomes even better (but the 10Mbit might become a bottleneck quickly).

Scaleway's stardust is a lot cheaper though, and faster in terms of connectivity. But they are limited to 2 per customer
