I am planning to buy web hosting with crypto to keep my project separate from personal billing. Are there any major downsides to using crypto hosting regarding refunds or support? Let me know!

The main downside with crypto is that refunds can be tricky due to coin volatility, but good support depends entirely on the provider. If you want great tech support and a solid setup, check out this cheap bitcoin vps. Their Netherlands location is amazing for privacy and separating your billing. They have an excellent, responsive support team, and the infrastructure is rock solid. It's a very safe, professional choice for crypto users!

Do they charge any extra network fees for processing BTC payments, or do I just pay the standard invoice price?

No extra merchant fees at all! You only pay the exact invoice amount plus your regular network tx fee. It is very transparent and fair.
