The right time to invest in bitcoin is when the price goes deep,as it dumps buy and hodl your coins,take a bunch of patience inorder that you will have the patience to wait for longer time before you reap what you sow.

How can you call the coin stable, when it makes +-60% in a few months? Nothing is stable in crypto. But it doesn't change the fact the the opportunity for making a good long position is the best right now. Just watch some graphs in the coinmarketcap and you will understand the possibility of ups and downs of any particular coin.

Actually, it is normal because the Bitcoin Market Review will show that its prices are increasing and decreasing. It's in a ring, and it's going to take us naturally. But I think there is no reason to be frustrated because I hope that it will soon smile on all the investors, the depositors, and those who are involved in the transactions. 

You can invest in any coin for the long term. The main thing is to determine the risk / profit ratio and create a diversified investment portfolio.
Bitcoin and Ethereum must be in any investment portfolio.

I think that's not possible for real life. You should stop think that the world currency will end up by start of cryptocurrencies, that's not how ot suppose to be.

I think research can help but it is better if you have a connection and knowledge. A lot of people are getting rich just on holding and investing on these volatile digital currency, it is easy but for a lot of people, volatility is not a joke. Even if you research, crypto will prove you they are unpredictable, you may still be even scammed by these cryptos.

When it reaches $7890,for the last two days the price of bitcoins was around $7600 as per preev.com so it is more cheaper than you mentioned so looks like the best time to buy some bitcoins.But no one knows it is the end of the dip or it will continue to fall so invest on your own risk and not more than you can afford to lose.And now we are at the end of fist half of the 2018 and th prices may starts to rise from the second half like happened in 2017 so it is the best time to buy.

A lot of speculations about the price of bitcoin this year some people say bitcoi can’t survive and some people still believe on bitcoin. I know bitcoin is a great coin that can survive this challenges, so for me bitcoin will rise high again this year despite of so many negative news and fud news about bitcoin.

Electronic money is facing a great challenge from governments and businesses. But promising bitcoin will still have a bright future. Electronic money is seen as a kind of asset. Human resources determine electronic money in the future.

Many people have freedom from global control. Bitcoin becomes a global currency even though each country has its own currency, bitcoin always persists and enters it. Bitcoin knows no national borders and does not waver because of the political conditions in government that have consistent

Now that we are seeing of many governments are seeing the blockchain as an opportunity to revamp their economy, here is a great article about China and the way they see the blockchain technology. I’m a token holder so excited that AML Bitcoin is the only patent approved coin that many countries will embrace their technology.

agree with the suggestion but some traders might not have that much fund which they need to buy hardware wallet for so in that case exchange is the only option and If you can take proper care about 2FA and email verification on withdrawals then you are safe to hold your funds on an exchange. But yes if the amount is higher then you must buy a hardware wallet to secure the funds.

To improve bitcoin, we work on bitcoin. We earn income at bitcoin. But we have to invest and do so that bitcoin is improving. And bitcoin will increase the rate of work and improve.

Anyone who believes in bitcoin will have the view that someday in the future bitcoin prices will be much higher and bitcoin has a huge role in the financial system in the world. If it continues to be maintained then bitcoin can become a well-recognized financial system, well we just wait for how the final governmental cyclical against cryptocurrencies. This will determine how the future will be achieved later. Government support will be very instrumental in the presence of all the mildew that occurs in bitcoin.

I understand that we have different ways on how to use our savings or when we will gonna spend to the extent that we will not regret our own actions. In my case, I still prefer my savings to be kept somewhere safe since I know for a fact that I will be needing that in the future. I also like the idea of investing my money to some crypto related business especially if I have the knowledge and extra money. For as long as I doubt in a certain thing, I would not continue doing that, on the other hand if I am sure enough then I would go for it.

I think they don't ban Bitcoin, just avoid it and just don't do transactions with it. Bitcoin in the current system is volatile and goes up and down unpredictable. Banks can't handle that kind of situations because banks handle money on flow, banks need to keep money flowing and not for holding. If prices of currency can change drastically in a short amount of time that would be major problem for banks. Bitcoin is stored online and I think banks are just useless for digital currency.

That's good thinking buy when price drops and buy even more because this is the best investment among all cryptocurrency. Catch this opportunity now price is still down from the last time high. We can hold once btc price going to rise again that's the time to sell.
