For nodes: Drive's are falling in price, 5g is coming online in a lot of places, starlink and Project Kuiper are going to bring high speed internet to a lot of places. I think once that happens, when you can get a RPi type box with 2 TB of storage you are going to see a lot more project nodes and things come online all over the place.
I partially disagree, you don't need very fast internet connection to run full node. Fast internet connection only needed to let your node download whole blockchain quickly.
Yes....but, you do waiting weeks to do the initial download will turn off a lot of people.
Also, add reliable internet. If your connection keeps dropping and you have to keep waiting to get caught up to send your funds or to look for payments also sucks.
I think current size of Bitcoin blockchain is around 330 GB, and with current yearly growth of around 25% I think that having few TB disc will last for years without any issue.
If the only thing on your machine is Bitcoin and your OS, yes. I was thinking about some poorer locations where you only have one PC so it's for bitcoin, surfing the web, doing school work, downloading videos, running quickbooks, etc. That can eat up drive space quickly.
