I think should be aware of market movement. Also, when you buy, do not buy in one instances. Buy in staggered order in small amount. Example when it dips, buy 25% of your money. If it dips further buy again another 25% depending on your tolerance. Be sure to buy only good coins, a coins that you have been thorough studied and trust.
Well i believe that buying this time is an opportunity. We can all see that the market are in dip. And we can really get more coin in a very few amounts of money as capital, I thinner need to buy today and hold for good we don't need to wait for the market to rise up high because market may rise or fall and if we don't buy it today maybe we can't buy it in the next few months because there will be a great posibility that it will rise and we cannot afford to buy it.
