Ethereum may have great future but it is impossible to predict its price for so long time

Waves gives to developers opportunity to create their own token, ticket, share or at least some kind of analogue of the real currency. At the same time, Waves has a fairly advanced programming language, which allows to speak about the presence of some similar moments with the Ethereum.

My view of this things are that there 2 type of people
1. People who can do business
2. People who can fund them.
In this situation I would invest in people who can do business and earn money for me, and this is applicable to the ICO. But of course there are many people as you said go to Hawaii after crowd-sale these are swindlers and they exist but we need to learn distinguish them

My advice is to divide your funds in bitcoin and ethereum and just hold them. You will see that is the best strategy on cryptocurrency market.

I believe that the price of Ethereum is partially get bubbled by numerous ICO, which at the end will cease to cost nothing, however, as the technology Ethereum is still the leader among all the cryptocurrencies.

We should spent more time to research technologies and only then make our investment decisions. Give me some facts why you think so.

Will be better to distribute all funds for zcash, litecoin and ethereum.

Yes it is really difficult to find the right crypto-currency, not to mention the ICO, but my advice is to invest in Bitcoin, Ethereum and Zcash. For thoughtful investing, you need to understand how technologies are working, understand how market is functioning, and experience will come with that.

I would recommend you to look at Monero/Litecoin/BCH and Waves coins.

Ethereum. Has grown 40 times in two years. You can create full-blown blockchain applications without intermediaries. What you can create: mathematically honest casinos and bookmakers, currency exchanges, crowdfunding, simple notarization, issuance and storage of shares for the company. I think it is one of the leading cryptocurrency for the crypto world in future.

If you want to invest for a short period of time, then it's worth to analyze the altcoins and try to break the jackpot, for long-term investments I prefer bitcoin ethereum and litecoin.

The market has quite a lot of interesting altcoins that have the potential to grow and bring their holders big profits, I would recommend paying attention to the Zcash, BCH and litecoin.

I think that IСO is an excellent opportunity to invest a certain amount of money in a project and get a good profit(sometimes as angel investors or bigger), but the ICO market is very young and is in the development stage so long as I would not call it the best way for investing but it has prospects to become it.

You can create just 1 wallet on "Ethereum Wallet" ( https://github.com/ethereum/mist/releases ). I think it's one of the best wallet (security, functionality)
 

I would recommend you to focus on 4 big points.
1. Team(background, previous project)
2. Technology.( you can ask people about technology on thematic forums and other communities)
3. Legal status of the token/coin.
4. Legal entity, location of the business.

Look at Monero, Zcash, Litecoin and Dash. I invested in them for long-term, they are very reliable assets and bring good profits.

It is worth to look at cryptotask.org ICO. I think it is my favorite project for investing.

Investment is always risky operation, investing in cryptocurrencies is very-risky operation, you can get a thousand-percent profit or loose everything. You must understand technology/business/token and only then start thinking about investing, not vice versa.

Will sell some of altcoins in hope of 10k$ of bitcoin but my position is to hold 40% in altcoins for diversification of portfolio.

I faced with this kind of an addiction a couple of years ago. The decision was to choose top cryptocurrencies and invest for a long-term. in this scenario, you will stop worrying about price fluctuations and over time, such excitement and will be avoided.
