Both coins are completely different and do not interfere with each other. In both, you can invest to make a profit. There can be no war between them!

There are so many coins out there now that have a good future the most important thing you have to just study first about the coin that you want to invest before doing it. There are some coins and tokens at first you look they are very good but in a few days, they already dump so choose wisely.

Before choosing the exchange you should first choose which currency you want to buy. According to the currency than see where it easy to sell or buy.
My top: binance and bittrex

I think Ethereum is the best altcoin. First of all, its price is really stable, relative to other coins. It can be thought as a long-term investment also.

Ethereum is a very strong project. But Ethereum will always remain second. It can not exceed the Bitcoin price. Well if I a wrong)

I always thought it silly to invest all my savings in one thing. Best of all, choose several promising and interesting projects and coins, and distribute your investments between them.

I believe that investing in ICO is the best way to earn more profit in just a few months, you will just have to be careful about choosing the right ICO

Ethereum is most popular altcoin and strong in fundamental, we can see it from the volume and the market cap nearly the same too Bitcoin, so this coin is good for long-term investment.

Yes, I think it is a good time to invest in especially in altcoins. Because most of altcoin prices are down. So you can earn the profit in a couple of months as the market expected to go up in the spring.

That's depending on the project and if it is having good potential or not. Sometimes it is better to sell the bounty rewards immediately, and sometimes you need to hold the tokens until the price increase highly.

If the ANN is bad and unprofessional I just scroll through it and usually, I find things that confirm my doubts so it doesn't take me more.
If I like the idea and vision of the project, or I think it could be profitable for me, I take more time and check the roadmap, technical info, if the project is transparent, if team members are real and so on. Usually, it doesn't take more than 30 minutes but depends on the project.

Altcoins price is affected by big currencies like BTC, Ethereum and there will be always dumped and jumps.
I think are good projects will grow price! (ICON,NEBULAS,Zcash)

I think mining on mobile devices is useless because it's not profitable. Maybe in future mobile devices will get such power, but mining will be unprofitable at this time.

I will never hold altcoins that long as it can be very risky as you never know when the price will crash so instead of holding too long I will keep on buying and selling regularly when it's giving me enough profits on my investments!

I think because it gives me the freedom to do my work as I wish. Either I get profit or loss it is my decision!
The cryptocurrency it has to change the world

Its cool, You are a proof that investing in cryptocurrency is not a scam and another proof that you can earn a good amount of money in crypto. I hope that more and more people will show interest in this type of investment.

If you have 1 ETH or buy it I think you must hold because on this 2018 the price ETH will increase. For get a good profit is on this coin, so this time you just must hold your coin and your life will be happy!

I usually check this forum to find out the good ICO. After  I checking project website to reach whitepaper, check Linked to the team's members and advisor's member. To find out the good ICOs, you have to have good economy knowledge!

The best way to reduce the risk of loss in altcoins is to make thorough research by following the announcement thread on the forum to know which altcoin is more substantial. Altcoin has great profit potential depending on the kind you choose to invest. You should also check the coinmarketcap to identify altcoins with bright future

ICO built on altcoin! If you decide to invest in ICO, you should know the risk you are getting into. Sometimes quality ICO can bring you a fortune if such ICO represents value for a market!
