By retirement benefits I mean when you're aged enough and you're no longer into bitcoin trading or investing more but you've enough bitcoin to withdraw and share, built family house, business and trains children. That's show you retired great.
This is the life that most people I know what for themselves but my question is why wait till 60 before you retire. You and retire with at 40 and have a great life with bitcoin if that is what you want. I am a fan of bitcoin but you make it look so easy. If you do not keep it safe, you'd lose it to hackers. I still do not think that anyone should have all their retirement funds in bitcoin which is still in a highly volatile market and anything can happen at any time. Before one considers this option speak with a financial advisor.
