It is not always positive when it comes to crypto and not everyone can accept crypto with open arms. There are also issues that crypto currency is currently facing and here's some of them.
1. Government Regulation - This seems like becoming an inevitable and the government's reaction towards crypto is aggressive and ain't welcoming.
According to a report by coindesk:
In late January, world leaders gathered for the Davos World Economic Forum, with several sharing the same sentiment
Also a lot of countries are starting to ban crypto.
2. Issue on inheritance - Example of this is bitcoin, due to its unregulated nature there is no other way to access the funds unless someone knows the keys needed to access the owner's wallet. But what if that owner passes away without telling anyone how to access his assets?
Another example:
Five years ago, Matthew Moody died during an observational flight, and at the time had been mining bitcoin. His father, Michael Moody, has spent the last three years trying to find out how many bitcoins his son has and how to find them.
However, without knowing every single address, he is unable to locate every piece of currency.
3. There is a security risk - there is always a risk on everything, even staying at home sleeping comes with a risk (like we don't even know if we will wake up from that sleep). Same logic applies to crypto currency. You probably saw some of my previous posts about hackings and scams related to crypto hackers can gain access to thousands of accounts and digital wallets where the cryptocurrencies are stored.
One infamous example was the Mt. Gox hacking incident in 2014, which saw the Japanese exchange close down after millions of dollars in bitcoin were stolen.
4. There is a market risk - crypto currency is volatile it can shoot up in a second and go on a free fall the other second.
