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.
You are stating that you are in the bitcoin market for a long time and are you telling that you missed out on the rally in 2017 since you said you are coming back after a few years and that means you were in a comma to miss the big rally that everyone witnessed. The market is in the same situation where you left but with a much bigger valuation and the market might rise again in a couple of years.
There isn't much difference from bitcoin, actually. the most obvious difference in terms of price. Of course you are very surprised when you see the current price reaches $4k right? even though in 2014, prices were still very low. and of course you missed the big pump last year, that's a pity, but it's okay. You can invest again and look for other opportunities
