Too many scams that FB needs to filter so they decided to just ban it all.
Imo not a very nice move with all these legitimate crypto companies not being able to advertise on FB, which offers one of the best targeting options.
Rumours have it that FB might come out with their own crypto, but nothing confirmed regarding that.

I would mostly recommend doing 90% of your portfolio into longterm positions and play around with 10% on shortterm trades.
The good thing about having the 10% on the side is that you can also use that to invest into coins that have dipped enormously and increase your longterm positions.

I would see ETH sitting at around $3k end of 2018, very solid coin.

The more projects that are built on ETH, the more it rises. I am so confident that this coin will rise this year. It's one of the (relatively) safest investments in the crypto industry imo.

I think the flippening will happen before 2020. We will see ETH rise as the king. BTC has started this revolution but ETH has really done a great job introducing smart contracts. More and more use cases for smart contracts are in development, once these will start getting used and projects like BlockCAT will be used by the general public we should see a significant increase in value for ETH.

OMG NEO STK ETH
All very good for longterm, DYOR though!

It's good because it stimulates every cryptocurrency company to appeal even more to the public.
It filters out the weak coins.
On the other hand it's bad for the new investors who jump into every single coin they can find and hope to hit the next ethereum.

The only way to regulate this without going with some centralized entity would be to use a site where people can vote on legitimacy of certain projects, preferably hosted through a smart contract on the blockchain. Would be a perfect project for someone to pick up!
The main thing now is to filter out the scammy projects from the legitimate ones.
