bitcoin rises again and altcoins suddenly pump.. Do not panic sell.The market always goes up and down and that it a permanent rule.    You can not change it

I think wait and hold,you know already how the bitcoin changing its price it was like when you wake up in the morning its too high and after 2 or 3 hours its getting low again.In fact this is the best time buy more bitcoin to invest.   we all know that bitcoin price is not stable, so if it goes down eventually it’ll rise up again big time. Just have faith and be patient

I just spend my money from bitcoin if it is needed.    because I do not want to spend bitcoin just for useless things,   :)better I keep bitcoin in order to achieve a good profit in the future. Im sure that with holding for a kong time would generate good profit in the future.

I like airdrop because airdrops are distribute free coins and maybe it is a surprise in the future, it is worth a lot of money.

There are still good upcoming ICO's right now  and I will still believe in ICO, because ICO gives me many advantages. Although, some of the scammers are using the ICO project to scam. We cannot call all of them as just scams

Every amount in crypto is important even if its small. Of course the more you invest the more money you'll make the end of the day    but you should invest what you can afford to lose

The right time to invest is to buy when the price is cheap and sell when the price goes up.It is at the moment better to hold the existing coin  because it has already decreased and if she has more money to buy coins which have strongly decreased.

 Here you can not just invest and be calm that you will always have a profit  , It is necessary to understand that you can lose at any time all your assets . I would rather be smart on my investments than being brave and reckless.

Many people don't believed in bitcoin maybe because  they don't understand this cryptocurrency  and  because the bad news of bitcoin is getting more and more recently, and the price of bitcoin is getting lower and lower, so many investors have lost a lot of money.

i think  it is not possible.Many crypto moneys have different structures     and i think  it's better to have multiple wallets because it is more secured.  Much better if you invest on a hardware wallet.

Bitcoin is really more important than ethereum because if there is no bitcoin then there will be no altcoins because they only get their idea from bitcoin to create another type of cryptocurrency that is called altcoin right now. despite the fact that Ethereum too is really having the most promising potential among altcoins. But still Bitcoin is the first used crypto currency and it have the highest price actually.

In my view, bitcoin is the gretest investment for future.. Risk also invloved.. Every investment plus and negetive points as well as risks. 
Bitcoin really helps me in making money, because I'm full time on bitcoin, I can focus on finding bitcoin and certainly make a pro fit.

I think depending on the need, when we are in the modern city then bitcoin better because many are accepted with bitcoin we can do many things, online transactions, pay bills, even for investment because the price that keeps and more profitable than others investment.

I dont store my money on banks    . I put most of my savings in bitcoins . 
I plan on holding bitcoins as much as I can as we get segwit activated very soon because it's going to make Bitcoin more attractive and new investors and demand is going to be on the rise for us too shoot up in value .

I prefer not to do that technique.        You can do whatever you want, but you should be ready to face the consequences also

 To answer your question bitcoin has a blockchain technology that I think cannot be hacked in any way.   but If you store your bitcoins in a centralized place/ wallet it might get hacked but if your wallet is secured properly bitcoin cannot be hacked!  

I think we must not worry about btc future...because digital era will long last forever..even more develop than now and btc will more brighter than now. Bitcoin popularity increasing day by day, the future of the Bitcoin will be Bright. Don't worry about BTC Future

Everyone expects that Bitcoin will last a long time.It's been a long journey of bitcoin ; maybe at that time the price of bitcoin will become stable and that more countries adapting it and more people will be joining band i hope that the price of bitcoin will soar high.  I'm more confident the bitcoin price will be higher every year.

we can not state exactly the bitcoin will survive. 
because there is no certainty in the world of cryptocurrency. 
only if I can predict. My prediction of bitcoin will last for decades to come.If some companies support it. Bitcoin would be hard to die out. We need also people coming to use it every day if we can to this bitcoin will surely hold out very long. 

I know there are no specific reason to stop buying BTC.    This platform is more stronger anyone can not destroy . no one can really stop someone from buying bitcoin if they want to. bitcoin is gaining more popularity as day passes by and this  means new investors coming in.
