What I usually do if prices are falling most specially if the coins are very low, I would buy more coins from a much lower price and your total amount of couns would then be divided; the result would be lesser losses. Read or research on google about books or ebooks on trading.
Absolutely right. That is what i always do and That is why i don't stick to only just 1 coin. Although bitcoins will always be my priority but i do have altcoins aswell though i am very choosy in buying altcoins. Because most of the time when bitcoins are falling, altcoins will be increasing so That my trading would be balance.
