Did you know that a few years ago bitcoin has dropped to a very low price, but in the + - 3 years bitcoin has managed to rise again.

in your opinion, can Ethereum go up like bitcoin? because at this time Ethereum's price dropped very much

The market is experiencing a downward cycle, many things are causing this to happen. but do not panic, if there is a down cycle there must be a cycle up so, we are waiting for the market to improve. we can also take advantage of this down cycle as a step to buy coins at low prices.

I think if Facebook makes their own coins it will be very good. their coins can be used to pay for Facebook Ads. this will greatly facilitate Facebook ads users. Facebook also has a lot of users, all of them are potential markets, but the most potential are Facebook ads users.

They have a reason for this, because most Bounty Hunter often sell tokens resulting from bounties at low prices, I see a lot of these things and finally all of them have an impact on the price of coins going down.
actually this is not entirely a bounty hunter but bounty hunters who sell coins they have at cheap prices, are involved in this problem. this is in my opinion.

until now I have not planned to choose coins to retire, until now I have only been looking for profits from coins and collecting them for additional offline business capital that I have run and some of my profits have been invested in Gold and land.

I expect more coins or successful ICOs in 2019, there is no need for much, little is fine as long as it's done well. I also hope, there will be institutions that oversee the new ICO so we can AVOID the scam ICO.

Why do you think the price of ethereum does not go up, whereas these days the bitcoin price goes up again? Usually when bitcoin rises, Ethereum prices go up ..
