1.Yes presently cryptocurrency market going Red. All the Altcoins going down very fast. So far not sure on the reason for going down. This is the time to buy into small portions.
2.Presently market is going down, I would recommend to wait if someone is buying and wait atleast this year end to make good profits. Not to sell your Altcoins in losses.
3.Ethereum is one of the very strong coin in the cryptocurrency market, the project very strong and its useful to cryptocurrency. The potential of growth also huge. It can beat Botcoins in coming years.
4.2018 year is going to be great year for cryptocurrency investor. There are many good news related to Altcoins to come. End of 2018 years people will end up with profits. I strongly believe in this.
Don't get me wrong, but your posts are vague and mostly in pointless threads where a 1000 signature spam posts are made every day. Merit is given by people who learn something from you, or even thinks what you say is worth merit. It is very hard to get merit in this forum, try learning more about BTC and crypto and invest your time in learning. Then you can easily up your rank when you make posts that are helpful.
This is the only way to keep this forum alive and worthy, and stop greedy spammers.
