I'm really tired of seeing stories like this and whenever I see stories like this it's usually follows with hundreds of comments with similar stories. There is nothing happy in those stories just filled with regrets. And these regrets are accompanied with pain and depression. People couldn't believe that bitcoin would be almost $100k now and they think about all that they should have done that they didn't do. But that time is passed and you cannot go back to change the past but you can start from today and make better decision about the future in terms of Bitcoin investments. There are even more ways to stack up Bitcoins than there were in the past.
True, those comments seems like there is no buying-back option... When a trader is always keen for price changes, always practices entry, exit, re-entry and exit where each exit his aim is to take profit. I don't think traders regrets their transaction when they took profit. After all, in Bitcoin cycles, there is always a door for re-entry. So I think those people who sold at lower price are still be able to repurchase when the price goes down if they decide to stay in cryptocurrency but obviously, those who sold and left for good do not even care...
A lot of people in this thread have got it wrong. The key difference is that Greg was not a bitcoin "holder". He was a bitcoin "trader". In the early days there was many traders, even I was one of them. There was not enough Bitcoin maxi's that never sold and held forever.
I wonder what is wrong in being a Bitcoin trader, as I stated those who trade Bitcoin always repurchase when price is lower and sell when in profit. They do it in a loop.
