10 to 12 times profit is 14 years is OK. Then it stops as per normal trading in financial markets. Now stock markets will most likely see -30% fall.
$400 to $7000 in 4 years for bitcoin is 20 times profit. This could be the reason Bitcoin starts falling from $6,700.
When will you sell Bitcoins ??
Well, I am not planning to sell just because its panicking right now and its trending down. It has more value than the current price and this is the only reason I am still holding and I am expecting to see the bullish trend to start soon in the Bitcoin and many other cryptocurrencies soon in the August month End. I am really having strong confidence on Bitcoin and i personally holding it from past one year because i entered my entry near 4.7k and i am still in profit.
