I think that Kucoin is a very decent exchange, I really enjoy how it works and how withdraw system is designed. For comparison (with same size exchanges) Bibox is a lot worse in my opinion.
I think that XRP will be probably pumped for several times in future so it is a good option to invest, it has a lot of holders so there will be activity around it.
Currently it is nearly impossible (sadly) because ICO sphere was the biggest catalizator of profit generating, now it is only trading which is very difficult.
Everybody awaits bull run for nearest time but I don't see any actual reasons why it may happen really... I think that we should cut our expectations on it...
1k is probably not possible for current conditions. Bounty shpere looks mostly like now, which is extremely sad because it used to be an amazing source to get money.
In current market it is absolutely impossible in my opinion. Even in past times it was not a very easy thing to earn several $ thousands was tough, now it is unreal, maybe even with investing.
I don't think that you can hesitate if you want to buy ETH because there's a possibility that its price will never be lower than now because 210$ is a total bargain for ETH.
I think that our pillars (ETH and BTC) are the best possible long-term investments because these are the only coins in which future I'm 100% confident.
I think that currently the most wise decision possible is just to not invest in new projects because todays market can't accept any new projects since it lacks capitalization for old projects.
It already changed the world a lot - blockchain technology today is integrated in a lot of areas of business and economics, I think that it will only continue to change the world.
