The list of best altcoins must be started by Ethereum, which is the second most valuable trading currency after Bitcoin. As one of the most popular crypto, you can buy Ethereum in any trading platform. 

I can not predict the market value today, but I think it's a good idea to buy and hold money for long-term investment. I believe that by the end of this year the market price will rebind strongly.

I do not think it's down to 50$. The market is volatile but I believe ETH will increase in the near future, I am sure so.

The most successful Airdrop events for investors include Bitcoin Cash, Bitcoin Gold, Stellar, Tron, Omisego. However, many groups use this to perform phishing. Also, talk about investing. I choose to invest in two currencies, BTC and eth, which are safer than another coin.

If you want to hold and invest long-term, you should buy BTC or ETH.
If you want to make short-term investments and make a profit, invest in altcoin.

Hello everyone, I am new but I have learned and mastered some terminology on the cryptographic market. I decided to invest some money into ETH and hope to make a profit after some time.

You should buy both, BTC and ETH prices are currently low, buy now and hold is a reasonable time. At the end of the year, I believe you will have a high profit.

Of course, I do not worry about anything, because I have confidence in bitcoin. Hoping that the price of bitcoin will go up sharply. Hold and wait, I believe bitcoin will not let us down.

Yes, the bitcoin price is much lower than in 2017, I'm in a state of hold and worry, hoping that by the end of 2018 the bitcoin price will rebind in the market to its true value.

Yes, ETH prices are dropping low, and this is the best time to buy and hold for a long time. I believe ETH will increase strongly in the future.

You can choose the Blockchain service, another option is Coinbase. Online wallets allow you to access your encrypted money anytime, anywhere, on any device. The security level of this wallet is just moderate, using an online wallet, meaning you have to rely on third-party support. If your trading platform is hacked and you lose money, your money will no longer. If the trading platform is attacked by DDOS or the access is overloaded, you will not be able to access your funds.

For those new to the solution to prevent the risk? Psychology people are attracted by high profits and rewards.
