It may be one main, most stable, trustful and popular. Like dollar on the fiat field. But like situation fiat there will be always a place for some local and specific cryptocurrencies. Even if they will be less stable, not so widely spread and less comfortable to use becaouse of this.

In long term it will keep going up and down. Untill really huge news will drive market up or down forming strong trend. For example - some big economics or some of central banks will unleash the war against cryptocurrencies. Or opposite - some big econimics will write loyal rules for free usage of coins.

Just because big part of existing and potential clients may be lost as a source of profit. And having competitor with cheaper service they will have to lower the fees for their services. That's way they support controlled Ripple.

There are two possible ways. 1. Invest in Bitcoin and forget about it until something happens that will drive it to the heavens again. 2. Invest in some very cheap coin, that is just starting and have some perspectives. Forget about this investments untill you'll starting to hear about this coin from media. If you want to try some more variants with expectations of real profit - better be ready to invest a bit more.

I don't think they will. More probable that they will create own cryptocurrency. And it will be one of the most expected ICO. If it will be ICO.

Satoshi and Vitalik now are trying to decide what to do with JP Morgan and Goldman Sachs and theit beloved Ripple

Today unfotunately Bitcoin more and more looks like tool of investment. Result of rising high in short period of time. To become a medium payment it must solve several problems, starting from proof-of-work.

I think it will only help Bitcoin to return on the right way - to become a currency for those, who want to be independent from government regulations, and not just another investment tool as it looks like now.

Both Trezor and Ledger Nano S are good choice. It will be no bad choice between them. I'd even say - must have at least one of them, if you are holding some real amount of coins.

In Ukraine everything is indefinite. You can buy a house paid by Etherium, but you can't simply buy cryptocurrency using your banking account.

That's why scam is still popular. Becouse some people keep paying money even when they understand that project is a scam. Behavior must be different - if you recognized scammers - wright a warning in all popular platforms. And don't give them a penny.

20$ don't look like investment, even considering a possibility that one ot them will grow high. At the same time there is not a lot of chances, that even half ot them will. So it will be more likely that you will lose money than earn. Probably it will be better idea to reduce a number of currencies and increase the investments in each of them.

Possibly Lehman Brothers will be secure enough decision 

Probably best moment to bet on Salzburg as Europa League winner.

Don't worry. Correction is an ordinary thing. Don't expect rally like from 4k to 20k. There is no such driver today. It will be moving up step by step. And regular correction is a part of this scenario.

Usually FB account may be locked when Mark suspect that account is not an accouunt of real person, but was registered to be used anonymously or under fake name for some purposes. Like participating in bounties and airdrops.

Not in the nearest future. Will need at least one really strong driver. Probably connecting with cryptocurrency legalization in some developed country or country with impressive GDP.

It depends from the reason you were blocked. I had only one warning about posts themselves. But had a lot of troubles with facebook trying to prove that I'm a real person, blocking account and demanding docs.

If you want to invest in ICO, airdrops are not something you should think about. You only have to recognize if it's real ICO or scam. If ICO will appear to be scam you will airdrop the scammers. That's only connectcion between those things.

At last some good news on the market Will see how it will work. First of all for verge.
