he applicate buy low , sell high
after 1O years profiting from bitcoin He calls it the riskiest investment one can make at the moment
as he already made lots of money, ie he already made huge profits now he is leaving the train, this would be something very normal, but he sell bitcoin to buy bcash was something kinda risky... if bitcoin drops, bcash and other altcoins also fall, unless those supporters of bitcoin cash still believe that bcash will overcome bitcoin and one day bcash will be worth $17000
So what? Maybe he needs money for something not related to business at all or he's decided to retire. I don't know how much he sold (can't find in any article) but if I had close to 1mil in btc, I'd sell them and enjoy the rest of my life with that money, invest in some business like a caffe, sit back and relax.
do business in real life is always safer, but open a business in real life is something very difficult, I for example want to open a company in my country and I'm already dealing with the processes, but there are many expenses with bureaucracy and construction of the company . As for the question of the source of this news, I would also like to know where the source link of this news
