I think I will never go further than top 50 because it kills the market capitalism and then it gets dangerous to invest into such coin. It will not take much time for such coins to get drained off and then make you loose your profits.
So its better stay above top 50 and then choose. For sure Ether is my motive for now and looking at the current rate of rising it looks to me perfect investment. The second coin is well within top 5 and thats Ripple. A very very good investment and very cheap at this point. Being centralised it stands all the time high in market capitalism. So these are two for now. And if third one then I will suggest Dash becaus somewhow it is keeping itself upwards when other currencies are down.
The most money I've made is from new coins outside the top 100. If you choose wisely and research you can find some real gems that will make you back 50 times your money, of course it's riskier but that's why it's high rewards.
Also Dash is a good coin, but it's not the right time to buy.
How it is possible to make profit with the outdated coin in the market place top lists bro. Please let me know what are all the coins you have to buy in the altcoin list. I understand that Dash is best currency all the time.
We find this in the market more an year here so let that alone keep aside. What are all the other you mentioned we will be able to make the more money with the trading or holding it simply for future profit.
