$1500 is not too bad, two years ago this time the Bitcoin is at $800? If my memory serves me correctly.
Hmm. More than a few people paid over 10x more for a coin than that figure. Let's spare a thought for them at least. It's likely that if they stay put they'll be fine but I'll bet they didn't sign up for those types of price levels.
Some of them have sold near the ATH and have made a decent profit, others have sold and something like $8,000 at the beggining of the bear market. $15,000 existed for a very short period of time, so there's actually very small amount of people who still hodl coins bought at that price.
