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

I was surprised, to be honest. One of my friends was involved in the crypto industry since 2014 and has strong faith in these digital currencies. Now he started a company and developed several products by his own team. Some foreign media always keep boasting about the popularity of crypto, but actually, just a very limited number of people know it and fewer engineers know it the underground running theory. So it's basically related to a person's philosophy. Some people hold crypto as a trending, while others think it's a disaster or threat to the current world and will extinguish very soon. So my suggestion is to be careful with everything related to investment. Don't count on overnight fortune.
