High volatility can be definitely point out as an obstacle and it is the most significant reason why bitcoin haven't progress in businesses because it makes majority of Organizations and clients hesitate to combine there businesses or make payments with bitcoin because in a little time it can do a big profit loss but we should know high volatility of btc is the main reason why many investors are attracted to invest in it but also it scare merchants away from accepting it but if bitcoin doesn't get adopted into businesses with the help of merchants its path to become a global currency will be much difficult so I hope this will change due to its increasing popularity in the financial sector
No mate. Crypto can even increase more because if a merchant accepts crypto , other people might be curious of it and they will soon try it out . now in case of loosing , its not the problem of the merchant or the crypto anymore but that is the problem of the trader because he is the one who is deciding for his funds .
