I'm very confident that Waves won't supplant Ethereum. A lot of the criticism aimed at Ethereum is based on current problems facing ETH, and says that in the future [insert ETH competitor] will be able to solve all of these issues, therefore this other coin is better than ETH. The distinction here is between now and future. If this other coin can in the future solve ETH's current problems, doesn't it also seem likely that in the future ETH will also solve ETH's current problems? ETH is a very professional project with very active and competent devs. I think ETH will be number one for smart contracts for a long time yet. 

Depends partly on the overall market trend - if the whole market drops since an ICO takes place, then the $ value of the token will fall below its fiat ICO price but maybe not below its BTC/ETH ICO price.
Another thing to consider is volumes - if a new coin is only listed on very minor exchanges and is only trading very low volumes, then the listed price may not be realistic - eg you can't buy $1,000 worth of the coin if there are only a couple of sell orders totalling $500.

I would say over $500 billion, with a chance of over $1 trillion.

We have seen wild fluctuations so far this year, but if you look at the underlying trend it is steadily upwards. Whilst with all the peaks and troughs it is difficult to give an accurate estimate, it does seem likely that the underlying trend will continue, and we will see a solid base above $500 billion.

A lot of the problems in crypto are due to its relative immaturity - it is still a young sector. As time goes on and crypto matures, many of these problems will go away...
Problems due to regulation - this is largely regulatory uncertainty and inconsistency, sensible and consistent regulation will evolve as crypto enters the mainstream.
Price volatility and manipulation - due partly to low volumes, which will improve as crypto gets bigger.
Altcoin prices being pegged to bitcoin - due mostly to bitcoin's marketdominance and to the fact that many fiat to alt conversions are only possible via BTC - again will disappear as crypto matures.

I think that many of the problems we face now are because it is a young market. In a few years' time, I think a lot of these will improve or disappear. Of course we may face a whole host of as-yet unanticipated problems...

Not really.
You need first of all to move everything out of that wallet, and then secondly set up a new wallet and notify anyone of a change of address for any tokens you are expecting in future (e.g. bounty campaigns).

Long-term - almost definitely up as smart contracts become part of day-to-day life

Medium-term - probably up as the potential of smart contracts becomes more apparent and as crypto as a whole grows, and as ETH POS becomes established

Short-term - who knows? ETH price will likely follow the whole market, irrespective of specific ETH news and developments

I don't know. I'm interested in the project, but I don't hold any EOS. I'm very wary of getting in at the moment, as the price is based largely on hype. Yes, maybe the price will go up a lot, but when other coins have been over-hyped they have suffered sharp falls. Maybe this won't happen with EOS, but I'd rather stay away at the moment.

I think that crypto will continue to expand - it has barely even begun to fulfill its potential in the real world. And for the whole history of crypto, bitcoin has been leading the way. Whether this will continue or not, who knows? With many new coins and tokens offering specific functionality and use cases, smart contracts etc., bitcoin has defaulted to become more of a store-of-value coin. Presumably this will continue to be the case. Yes, there is a chance that it could reach $91k in two years' time, but then again things can change. There will be many bumps in the road, and many issues to overcome. What will happen wrt scaling? Will LN still be a thing? etc... Crypto prices have proven to be wildly unpredictable, and putting a specific price on a specific date two years down the road seems like a strange thing to do.

Contrary to a lot of others, I do think XRP is a good choice. But I would split your money across more coins, and get some ETH and NEO as well as some BTC.
It's all personal choice though, everyone has their own perspectives and opinions. I do think that XRP price will rise, one thing to watch out for with this coin is that price rises are often sudden and dramatic, fuelled at least in part by the traditionally overheated South Korean element.

I'm another one who is bullish on 0x. Yes, it will have competition, but that just proves there's a need for this sort of project. Developments and the future look promising, I will continue to hold.

It is always a good time to be holding Ethereum. It is a very solid project with big adoption and huge potential. As the upgrades continue to be rolled out, problems such as network clogging will gradually fade away. I think that ETH has a very bright future.

It is not a huge amount, so I would say just keep it as ETH.
If (when!) the ETH price goes up significantly, you could maybe siphon off a small percentage to put into other projects.

It may happen in the long-term, but short- and medium-term this looks very unlikely, either in terms of market cap or individual token price.
NEO is a great project, but so is ETH. And ETH has a big first-mover advantage.

But as with almost everything in crypto, we are still in the very early stages for both projects. ETH is still being used
mainly as an ICO platform, but its potential goes way beyond that and smart contracts can in future reach a long way into daily life. Same for NEO. I'm not saying it definitely won't catch ETH, but if it does it won't be anytime soon.

One thing to be wary of is those airdrops that have KYC requirements.

Remember that we have seen a number of airdrops that are phishing scams, trying to get personal data and/or wallet private keys.
Airdrops in general give only a very low reward, so you should think very very carefully before submitting any KYC documentation.
Personally I think it is not worth the risk at all.

Just be careful, everyone! KYC is becoming more and more commonplace, but is it worth the risk for a few free coins?

Some campaigns are better than others, and some are quicker at paying out. It is understandable that companies may not want to pay out bounties as soon as the coin is tradeable - they really don't want to see their new coin tanking in price as a lot of bounty recipients dump the coins at the first opportunity.
Projects that don't reach soft cap is a separate issue - this means that the project has failed to gain sufficient minimum funding to be viable, so the project stops. There would be no point to receiving coins in this instance as they would be worth $0. It is a risk we take I suppose, so we should always try to back campaigns where it is a strong project with a good chance of success.

Crypto is still very young. Prices for almost every coin are based largely on future potential. We are a very long way from people running out of ideas. As crypto matures and becomes embedded in everyday society, and as technology advances, new problems will always arise - and new solutions will rise to solve these problems.

Look back twenty years to the dotcom rush, and all the solutions that were offered then - and compare this with big websites that exist and prosper nowadays - in 1998 it would have been very difficult to envisage some of the internet problems and solutions that exist in 2018. It will be the same with crypto.

I think there is no need for concern on this issue.

I never bought EOS because I don't like the way the ICO is run. Not saying this makes it a bad project, but it does help to make it a coin whose price is largely dependent on hype. And this gives a big warning signal.

We do see this with a lot of projects, and in general once the hype reaches huge levels it is a good time to sell. Even if it is a good project, you will have better opportunities to buy back in at a cheaper price later on once the hype has died down. We've seen this with so many coins. Cardano was a recent one, and before that IOTA.

If you see something racing towards the top in marketcap, but they don't have a working project yet - then just be aware that what goes up rapidly often falls back just as rapidly.

Airdropping a small proportion of coins is a good way for a new project to develop publicity and interest. This is why airdrop conditions often include having to retweet or share social media posts.

The reason there are so many of them is really a good sign - there is a lot of interest in crypto now and a lot of new projects appearing every day.

I know this post is more than a month old, but it is still worth mentioning that Tether isn't absolutely safe. It may have a stable price around $1, but it isn't the same as $1. There has been skepticism of Tether in the past, and the subpoena. It is relatively safe to use short term, but I'd question holding Tether for a longer period.

I like most of your 10% coins, not so keen on the 5% ones.
I would be tempted to go for Waltonchain in preference to VeChain. Also I would recommend getting some Ethereum and Bitcoin.

Just personal preferences though; everyone will have a different opinion.
