I simply choose Bitcoin because of its sustainability, and profitability wherein you can do both trading and long-term investment. Not only that bitcoin is the mainstream cryptocurrency but because it has the most market share and highest trading volume in the market today.

Ethereum is more promising this 2018.  It may not reach the price of bitcoin but it will rise higher than btc in terms of profit and percentage.  There are lots of ICOs that uses ethereum as well as it is used as gas in some transcations.

We must set the target how much we can get from the amount of coin that you have, and sell it when the price is your target to sell it, and the price must higher than ICO, that is the best time I think

You need to determine how you understand what Altcoins is and your ability to withstand risks. You need to take some research to have knowledge about the trade. You must be careful to make exact decisions. You must take risks and learn from your mistake, is the only key to success in trading Altcoin

You can buy an ICO token. I never sell my Ethereum until I get a lot from it. We need to invest more in Ethereum, not just in Bitcoin.

I always buy Bitcoin when it falls, because I believe that the Bitcoin community will support it, no matter what happens to it. Do not worry that these falls have already occurred last year at the same time, this is the usual thing you need to take in the crypto currency

The cost of coins is so low, especially high-quality coins with promising projects, you better hold on to these coins until they return their value

You must carefully study the ICO before participating in its campaigns for generosity. If the project has some potential and the expected success, then you can join its generosity, because such projects have good teams and developers, and they give valuable tokens as a reward

If you want to invest long-term, prepare a lot of capital for maximum results. Because, if only a small capital, its profit is not felt. I advise you to invest in BTC or ETH.

More and more ICO is conducted on the Ethereum platform. This pushes the price up. The best time to buy was a week ago, but I believe that it's still not too late. You will still have a good profit if you keep it for some time.

I do not agree with you and the person who said that all the altcoin are just scammers. Perhaps some altcoin were scammers and fled after collecting funds through the ICO. But that does not mean that everything altcoin is fraud.

I still keep my coins until I know that I expect the price to go up. You will not lose your money that you use to invest in a token if you are selling it at a higher price that you are investing.

I plan to continue to invest in crypto and keep coins for a very long time, crypto has a very great future, as it makes the world more global and creates secret transactions.

NEO managed to continue to grow in the Chinese market, which explains its significant growth, and this can lead to a better future, so that it is in the top ten of the currency. I believe that neo has a great future, after China admits crypto currency, the price of neo will fly to the moon

The first thing to do is learn and research ICO, which means that we need to know about the team of the company that is the manager of generosity, read the technical document, how they promote the program, what they produce.

All depends on what you want to gain from holding. Many coins on the market are made for reason their creators want your Bitcoin and your money. I advise you better keep Bitcoin for a long time

The company bounty is very popular, and thanks to participation in them it is possible to get tokens, but choosing which company and project is fraud, and how - no, it's really difficult. The forum already has themes that specify the items and parameters that should be considered when choosing a company

The market is unpredictable, anything can happen at any time in the market, but soon it will recover after it fell. So do not worry, soon it will be restored, and everything will be fine.

I fully believe that bitcoin is the leading coin, and it shows its importance on the market. We all know that bitcoin is the most popular in most regions of the world, so that the market is under the control of bticoin

Not everyone is selling their bitcoins now, because they are afraid of losing their money, perhaps some of them have their own problems with money, so they sell it at such a price.
