good question....I guess what you anyone can afford comes into play and know this is going to be very volatile on the upside and downside...but overall we have seen forecasts that suggest that perhaps this is really a time to digital currency migration. IF that is the case --- the BIG money has not arrived yet and will be an ongoing process for years and years and so now is a time....next month is a time...if it goes to $6800 very fast and you know it could pullback 30-40% ---- 30% of $7000 is $2100 ...so it pullsback to $5000...does it go to $13,800 by Q1 next year --- this is the question. Nobody can tell you when -- only you. And only you smile, frown with your investments.
