Purchase low offer high that is the most ideal method for trading,if you are not following that manage then you can't gain while trading.I am not a merchant but rather I am holding bitcoins too.So when the cost tops up I will offer that on the grounds that there are more shot of cost fall after the quick cost increase.Then I will purchase more coins when the cost dumps.I trust the vast majority of the general population are doing in inverse direction,many of them willing to purchase when the cost increment and will offer when the cost falls.
