I think I'll sell them and replace them with ETH, and then invest in the ICO project, because choosing a good ICO project, the rate of return far exceeds the investment BTC.
Cardstack is a good choice, and the ICO project code is completely open source.

First, there is an ANN thread in bitcointalk about the ICO project，A good ICO project will have a ANN thread in bitcointalk
Then follow their twitter and telegram, so their followers can judge whether the project is hot or not.
Then search for the open source code for this project in gtihub.

Because the entire cryptocurrency market is in a bear market, investing in ICO has become a risky business.
But can still look at Cardstack, which is an open source project, and it has a high degree of integration with the block chain.

I think that the gambling of cryptocurrency is simply to avoid the regulation of the law, so there may be more black curtain.
But if blockchain and gambling can be combined, it will make gambling more public.

The only way to make more money from cryptographic money markets is to hold them.
A lot of people because of the short term there is a drastic fluctuations choice sold tokens, so this is not a good way, because when the price of these tokens very quickly rise, you might miss.

Why do you think IOTA will be the next ETH? You just mean the price?
IOTA and ETH are two different types of tokens, so it's hard for me to find a link between them. The only point of contact is the price.

Although POW mechanism and POS mechanism have certain advantages.
I think the price will go up after we switch to the POW mechanism, and recently in the bear market of cryptocurrency market, I have bought a lot of ETH, waiting for its further rise.

 I personally think POW mechanism is better, because it need not spend a lot of manpower and electricity in token, but POW mechanism is faced with a very serious problem, so any one can issued a token, the cost of fraud is too low.

I think first of all you should choose a good ICO project, you can find your favorite ICO project in some ICO evaluation website.
Second, choose a reliable bounty manager, try not to choose those grades only for JR members and members, there should be no guarantee.

I think most of the time it's ok，Although China has banned ICO, many ICO projects still do not prohibit Chinese participation, and I don't know why, it seems that China's ban is not strict.

Why do you think bitcointalk forum is the equivalent of bounty?
Posts in this forum, every day still have a lot of technician chat on technology, because the early investment bitcoin and join the bounty threads, they make a lot of BTC, but that doesn't mean they can't continue.

I don't know why.
But most of the altcoin will have a similar gains, if BTC in a relatively stable price, so they will gradually rise, this seems to be the rule of encryption in the cryptocurrency market.
So as long as bitcoin is on the rise,cryptocurrency market is a bull market.

I think the telegraph group is an important reference standard.
Because of the number and activity level of the telegram group, you can find most people's views on the ICO project and the prospect of the ICO project.

I do not look good LTC, because the founder of LTC has sold all his token, and sold in high price, it's hard to not let a person feel he had not manipulation market, and LTC compared to other altcoin no advantage.

Japan is an advanced country, and since the second world war their ideas have been better than those of ordinary people.
This is why the Japan can become a great power, because they can always accept new things quickly.

I've bought a lot of it at $7,000.
So I think I'm going to keep buying it at $5,000, because I believe in bitcoin, and I think bitcoin is going to be part of our future, so why not buy it?

But I think it's just hype.
Because the cost of using bitcoin to pay for Fried chicken is too high, because the transfer fee is more expensive than Fried chicken, and my Fried chicken is cold when the transfer is confirmed.

I think this is possible because both the us and South Korea are going to hold a conference on further regulation of bitcoin these days.
The entire cryptocurrency market is still in a funk, so further falls are normal.

I think Chinese New Year has a big impact on the price of bitcoin.
In the last few years, the problem of Chinese New Year caused the whole cryptocurrency market to fall sharply. I think after the Spring Festival, the cryptocurrency market will rise again.

If you want to buy altcoin, then I recommend you buy ACT and QTUM. There are many ICO projects based on ACT and QTUM.
If you want to join ICO, I recommend you to know about carastack.
