For others unlucky enough to join at the high, it was a most unfortunate event and 80% has proven to be intolerable for many of them.
Sorry, 80% losses are never just fine.
It was a risk assumed by those willing to invest in something up over 1000% in the last 2 years. Despite 2018's heavy decline BTC is still up 320% over the last 2 years, making it one of the best performing asset categories within the same time frame.
Besides, compared to all other cryptocurrencies, BTC is kicking butt. None of your altcoins have performed better.
Kicking butt implies making profit.
Fact is all coins profits are in the shitter right now.
There is no kicking butt, by any coin right now, they all suck!
