Forget about #0, it's a joke from coinmarketcap. You can't buy it anywhere. If you have just clicked it, you'll read the note that it's made and listed for the joke.
You're not left behind, you just missed the opportunity of buying the bottom and you're still in good time to invest if you're one of those people that believe that bitcoin could reach more than $40k soon.
Hmmpp..I am interested to know what could happen to bitcoin. There are really great surprises ahead and that could be mean that btc could go in just a short period of time having 100K $ per btc. It would be possible and we all know of that.
It is one price that many are saying, it's not too late to buy until you've got spare money to spend.
