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
