Not selling you coins ever is the worst thing to do, if you are earning profits you should sell it and again wait for the price to fall down, do not hold your coins too long.
lol after you get slaary or income. i think dont directly sell mate. you must see and watch the price first
Ech. Not necessarily the price. The price tells you nothing - you need to look at the trend, and the recent news and how they'll affect the price in terms of demand. Are there positive discussions relating to Bitcoin and could possibly support the demand for them? Go ahead and buy. The price is likely to increase that way. Some huge scandal involving bitcoin occurs? Go and sell. It's obviously NOT as simple as I depict it, but honestly, it's stupid to hold ALL your coins. Obviously, don't sell all of them and become an absolute bear, but play around with some of it.
