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

Cryptocurrency as you know it, hasnt changed much. Yes, there have been advancements and one of which is that it can be acquired with many means. The originally known means is via trading, then some other means too, but by being in this platform with us, the most common means is via ICO initial coin offering.
Welcome back to the crypto world.
