I think the reason here because the ICO owner sold their ETH to get money, especially those scam projects. They will sell all of their ETH to get their fiat or coin, that is a fast way to make their scam project disappear

Maybe but I think this is not the major factor why ETH drastically dropped, there was something behind of it. Base some rumors because of decline trend where as all altcoins and bitcoin experience also  the beaeish market. Soon I believed they will recover.

Looking at the decentralized nature of crypto-currencies,Wonder if govt bans Bitcoins in future??Is it possible let's say by blocking all sites which relate to Bitcoin wallets/payments etc over the internet.In that case what would happen to our existing coins held in those wallets??

Actually, in my perception if the internet connection will going to ban as well by the government, bitcoin for sure will not able to used. In some site also will gone like facebook, twitter , google, youtube and etc.

Trading is like an addiction, but this bear market seems will be very long. Bitcoin is going to under 4k USD, ETH is now 110 USD, Almost 80% coin fell down. I can't make profits at this moment in trading, Because after getting a little bit of profit, the market again goes under, then another coin eats my profit too. What should I do now?

If you observe the bear market is still on, you should keep calm and hold for while and wait for the right timing to buy and sell in cryptomarket. Now the eth is really struggle its value which is nearly going $50 value. I hope it will recover as early as possible because i had invest eth when it was $100+.

Few days ago people mentioned that Satoshi made his first publication for the last several years!
He wrote a word "nour" which probably means "great"/"nice".

What are your thoughts? Do you think it means Bitcoin is gonna rise soon?
Or he's happy because of a market death?

In my perception i guess it means the bull run coming and we should prepare for that. We dont really know whats the real mean of that nour, Im just trying to be keep enthusiasts in crypto especially in bitcoin because i believed bitcoin will rise soon.

For me, I look first the bounty managers whose have a good reputation in the forum because nowadays its hard to choose which is the legit bounty that could guarantee you will be payed after campaign. I had many times experienced of not being paid by the bounties, thats why im very careful now by choosing. Its not easy to make effort in bounty task and then  you did nothing in last.

In my perception nobody will replace bitcoin technology to its place. There are many altcoins were has a potential, but if you notice the whole market when bitcoin drastically dropped, all altcoins drop as well. It seems all altcoins were depend on the bitcoin.

I am sure that after 5 years Bitcoin will be more popular as this coin will begin to be accepted by Government.This will soon be used on all transaction like banks and billing payments.

Wow! I guess youre a furtune teller mate No one knows and predict precisely what will happen in the future of bitcoin. The only that i think about next 5 years bitcoin will gain more fame as more people will get adopt on cryptocurrency.

My motivation is my earnings. I always believe in long term investments because it always proves to be profitable in the long term. Please provide your views.

I agree with you mate, but you make it sure you invest in high profile and reliable coins which is proven effective for long time Investment. Just like bitcoin it is the biggest example for long-term investment and my second option is etherium.
