It all depends on how much efforts and hard work you put in which will decide if you will be able to earn some good amount of money because of the crypto currencies or not. If you are having this much of the skillset and that you believe that you can do better, then you will surely be able to make some good earning and that this will turn out to be the best possible ways of making money.

You will be "rich", potential coins 2018
  for now it is very difficult to choose a potential coin, but I will
always trying to get it, although it is currently not visible,
at least though I have to wrestle with fatigue, but I'm sure it must be
this year 2018 I will get a very potential coin.

There have been a lot of other alt currencies, but don't seem to have what Bitcoin does. I think down the road potentially, but as of now the focus seems to be on how to make Bitcoin better, safer and more accessible. We're pretty bullish on it.

I doubt that , however there might be a currency that will do very well more than bitcoin , e.g in fiat world where you have different currencies doing very well

Bitcoin is getting  a huge shield around it, several and important projects are being made to protect and improve bitcoin, augur,zcash and openbazar, and with those projects looks like bitcoin wont be replaced so soon for any other altcoin.

I see very very less chance of it happening. Because bitcoin is the pioneer in crypto currency world. The market cap is already huge which shows the interest of the people in bitcoin. So it is hard to replace bitcoin.

But on the other hand I won't say that it is impossible. You may have some other crypto currency which may grow up to bitcoin's level in future but probably that currency won't have the power to replace it. It is just that people will start enjoying the fruits of that currency as well. That will be only good for the crypto currency world only.

If most of the people will truly remove their trust in bitcoin, no way they will trust other crypto too.

After all years that bitcoin really takes some good and positive progress, adoption, usage and development and still got wrecked you think people will trust other crypto too?

Bitcoin has had a huge advantage by being the first cryptocurrency ever. Its market cap is 10x larger than the closest competitor in terms of market cap (ethereum).
It also has received significantly more press in mainstream media than other altcoins.

Since many altcoins have more advanced and complex features over bitcoin, they are even harder to understand to the ordinary person.
Try explaining "smart  contracts or the dao to someone with no knowledge of cryptocurrency and you will understand.

At some point bitcoin will be overtaken, just because it is far behind in its technology, but the question is how long that will take. No coin has gathered that kind of momentum since bitcoin.

The popularity of bitcoin is limited to digital world, not everyone knows about bitcoin but when it comes to crypto currency I think bitcoin is the best and it has no competition around.

Finally! There's only a few people who realizes that Eth is a scamcoin and a lot of people are taking huge investments in it. Bitcoin is probably the only trusted coin there is. Well, litecoin almost made it but I'm not sure exactly what happened.

72 million eth was premined and is in the hands of devs. Hmm i wonder what could go wrong here...?

Ban all scammers from forum and I will leave myself 

It is much better than oil. It is not subject to maniac actions by Middle Eastern monarchs.
But this guy seems to be pushing for increased adoption of electronic rouble. That won't help much.
