Irreversible Payment:

There’s no center point in payment processing so if you transfer money to someone by mistake and want to get a refund for services there’s no option to dispute that person and the only way to get your money back is to ask the person to
refund payment and if he/she refused then you may as well forget about it.

Not Widely Accepted:

There are not many companies or websites who accept cryptocurrencies, and if you have some cryptocurrencies and you wanted to purchase something from website and company then you have to search first which service provider accepts crypto currencies,even if you don’t like their services and have only cryptocurrencies then you have to use it even if you don’t like that service, also bear in mind that in physical stores you have to use real money instead of digital money

Losing Your Wallet:

If you stored your digital currencies in your system or mobile and if you lose it then there’s no way to get your money back and you are unable to complain to the Police or any other similar Authorities. However, there are still ways to keep safe, like keeping it offline.
