First of all, my bitcoin stash is really tiny. I wish I had bought more coins in the past when BTC was still dirt cheap (at least comparing to current price)
We need to understand something, money, bitcoin or stashing your riches is not end in itself. I will sell my Bitcoin when I will be sure that it could change my life for the better.
Or if I realize that I need to indulge myself. Don't wait until you will be old and sour, catch the wind in your wings today.
