Hi All,
I have been in cryptocurrency since 2014 but last 3 years I took a break from it. I had high hopes how it can change the financial world.
I would like to get back into it but first I would like to find out what is cryptocurrency today.
Is it just a trading commodity, long term investment or is it (very very very) slowly replacing fiat. I know there are many companies and small shops that accept cryptocurrency but is that it? Is the problem still about the speed of a transaction
Please help me catch up a little

There are a lot of changes that we can see nowadays, there are now governments that legalized cryptocurrencies in their country. They say that it is now preferable to use cryptocurrencies than fiat currency because of its convenience in terms of transaction.
