In 2009 bitcoin was launched. It was worthless at the time. People wasted what they have. Today, I am sure many are regretting not taking bitcoin serious. All of the cryptocurrency is an emerging technology and ecosystems.

Dogecoin is just a funny rofl-coin, which found some support from the community. At the time, a couple of years ago it was a good coin - low fees, high speed, easy to mine. But in 2018, I do not see a great prospect. Now there are many coins, much faster and cheaper.

I would not call the crypto is bubble. Crypto is a new market, very young market with big volatility and so often it happens that first there is a strong growth, and then a strong fall. So it was with the shares of various companies in the Wall Street, with other assets on the stock exchange.

As we can see, at this market, 9.5 btc more stable Unlike ETH.
So BTC is better to hold now.

I hope that we are already close to the bottom and soon we will see market recovery.
But before that I think that we once again descend to the level of 5000-5500.
It is necessary to look what decision will make SEC in relation to ETF.

The market is in on downtrend, so I try to add to my bags some Bitcoin and Ethereum.
Also i'm buying some other alts like LTC, XLM, ADA.
When the trend changes i think this coins bring nice profit.

ADA is a good altcoin with a very strong team and product.
10 is a very high price for my opinion for that total supply of coins, 3-5$ is more realistic.

Yes you can, the market is very volatile, and while everything is not stabilized, everyone can make money on it, but also someone can lose money.

As an example, this is a perfect time to buy more altcoins and to try to stack as much as you can from all of them, the prices are cheap and you can make some money. But there are some that are never going to recover from the last crash, and we all know that.

Judging by the current market trend, it is extremely difficult to expect short-term profit. Because the market keeps falling and falling. And in a falling market is very difficult to trade. Therefore, only long-term trading.

It is possible to choose projects which in the future will be very in demand. Basically there are projects which have a real product or are of real benefit to society. I have always recommended to invest in such coins. I think that the most promising are ripple, NEM, WAVES, Monero, ETH.

The bitcoin price is cyclical, the fall will always be replaced by the growth of the price. Therefore, we should not worry about such trifles. After all, peace of mind - is the key to successful earnings.

If you believe that the coins you are currently holding had potential for future growth and will go up soon after the bear market, then just keep holding them till the green is back. Strategy and tactics will be useless unless you are well-informed on the coins you are holding including its developer and upcoming developments.

Yes, of course, the ICO in 2018 is not the same as in 2017. 2017 is the boom period of ICO projects. Most of the projects are profitable for investors. In 2018, the electricity price has fallen, ICO projects no longer attract investors as before.
You need to choose project carefully.

The answer is money.
Many projects only try to raise a lot of money.
They don't care about the product or something else. They just see how popular crypto is and try to earn.

The market is not that good right now.
But for me, it is more safe to invest in a long term coins like BTC/ETH 50/50, maybe add LTC or XRP.
Good luck!

Look at the 100 richest wallets of bitcoin.
Most of them only accumulate bitcoins, while they are cheap.
So no need to panic sell.

Of course, there are a lot of scam projects now but i think this isn't the main problem. For me the main problem of ICO now is the availability of ICO for everyone. There are no specific requirements for companies that want to do the ICO. Therefore, there are so many scam projects and so many projects that don't have a product, professional team, investors, experience in their fields, etc.

It all depends on your project and your investor base. In the current market conditions, most investors won't wait and sell your tokens to stop further loss. On the other hand, it may be a good idea to hold it if a project is close to a working product or some important updates.

I do not believe that all the altcoins are scam.
Yes, the market also has many scam altcoins. And after 2-3 years we will have forgotten these altcoins. But I think there are many altcoins that are not scam. And maybe in the coming years some altcoins prices will approach the bitcoin price.
