• Irreversible: Most of us know that BTC transactions are final and not reversible, and as such, if you send to a wrong recipient or a wrong amount, it becomes a really sticky situation. A lot of people tend to keep their digital currency in a cryptocurrency wallet, which puts them at rusk of losing investments if there is no longer access to their private key.
Yes. But if the transaction is not yet confirmed, it can be reversed.
•Volatility: Satoshi Nakamoto imposed a limit of 21million Bitcoins, and then, it was regarded as totally scarce. That contributed to Bitcoin's value. But also contributes to price volatility. Bitcoin's decentralization also implies that no minimum valuation is guaranteed, that is to say, if a large group of investors stops using Bitcoin, and sells them off, the value would significantly drop , and people with large amount of the coin will be affected
But it has been the opposite. People are buying and the price is increasing more than decreasing. Bitcoin is an appreciative asset.
•No Government Regulations: While decentralization is considered as an advantage of crypto, it can be seen as a disadvantage of Bitcoin, given that it implies there is no investment regulations.
Unlike a currency regulated by a Central Bank, Bitcoin transactions are not accompanied with legal protection, and given it's irreversibility, makes it scam prone.
The reason it is not a depreciative asset, unlike the fiat control by the government which is a depreciative asset.
•Not accepted everywhere: Even as the rise of cryptocurrency is upon us, Bitcoin, still isn't accepted just everywhere. Major companies now recognizes Bitcoin as a means if exchange, it's still not widely accepted. This puts a limit on where you can spend.
Bitcoin is decentralized. Do not be surprised that people in the countries it is not accepted are having it and trading it.
