Yes cardano is having great potentiality and also team involves one of ethereum founder but the supply is huge even trx Aldo same . Both having great team with awesome concept with excellent market strategy but still having higevdupply that is the only main disadvantage with these coins.

There are quite a number of interesting upcoming and ongoing ICO's. A few of which are BeeToken, Envion, Coinvest and Nucleus Vision. They're worth checking out, but do your own research before dropping some money on them.

My biggest mistake is trading on the stock market for my money, especially intraday trading. I do not advise to do that.

so far im satisfied with hitbtc, okex, idex and etherdelta or forkdelta, maybe many other major exchange who is better than im mentioned ilke bitrex, binance and etc, but im prefer with that im mentioned.

I guess altcoin is too risky to invest always. Cryptocurrency is very young and unexpectable market. Before investing you should spend some time to learn about  sphere where are you going to invest, its help you to make right decision better then listening someones advices.

From the point of view, it's time to buy ETH since the price is not high enough. Although it drops sharply, we believe that the price will recover soon. What we should do is to buy as many as possible and hold them as the long term investment and one day you will get a big surprise.

Cryptocurrencies will not kill cash in near future. Don't forget that there are still billions of people without of internet and computers. Cash is still the only trustable solution for them. But long term maybe it will be possible.

I like NEO and I thinh that it show's a good chart's now and need seriously thinking about buying it. NEO have a useful platform and this is a base for a many token's. I have ZPT token's and GALA token's in my Neo wallet. I think - that NEO is one of the most surely good coin's.

BITTREX - Go to Bittrex, The Next Generation Digital Currency Exchange and sign up. Get your BTC or ETH address. Transfer BTC or ETH to Bittrex and send your exchange it with NEO.
