what's stopping you from accepting Bitcoin for your business transactions?
Let me speak for most according to my observations
1. Ignorance about Bitcoin
2. Demonization of Bitcoin by their Governments and Central banks. Some countries still deem Bitcoin as illegal.
3. Some of them feel or think that the process using or carrying out Bitcoin transactions is too technical for a layman
4. Yes we are in 2025 but some business lack the infrastructure to accept online payments. Shocking, innit?
