I changed my mind so if you have 500-1000BTC in the near future can result in millions of dollars if the price hits 1k to 2k, so maybe 1million you can retire, but in 20 years count a zero less so around 50-100B
500 is nice amount i would be happy with 50 at least
Barcelona vs Granada i was bit surprised why the odds for Barcelona win is very low @1.02 and i already know Barcelona is strong team in spanish league but doesn't mean Granada will lose with easily
