I did told myself to sell my bitcoins when i hit 6 to 7 bitcoins, though when its price is really going up high and really crazy i dont know if i want to sell it or maybe just convert it and buy some things. Though i do really want to sell some.
If you refer to all your Bitcoin holdings, I think selling everything could be a mistake. In the same way, I also think not to sell anything, if you need the money, it may be a mistake, as price could fall again, and you would have to sell at a lower price.
i think i currently missed the right time to sell but in fact it was expected that the price of bitcoin will cross 1200 USD therefore we wait. now as thee price is trading below 1000 $ therefore there is no chance to sell in such a low price i have to wait for next few months when the price will hopefully cross 1500 $ level. therefore i will suggest that those who are already holding bitcoin should wait and those who do not have bitcoin, they should buy bitcoin even in current price and then hold it for the price increase.
