Hello comrades!  
I recently started to be interested in crypto currency, but already during this time I was very excited by this.
Bitcoin on our eyes now, again began to grow. November 11, I bought for 310 dollars, now I have already 370 on my account.
Will the bar exceed 8 thousand and will it stay stable for 2 days?
Do you advise leaving small savings or still withdrawing?

I' ll take bitcoin as an example.

Is it mandatory that the value of all bitcoins is equal to the value of the world economy?

Can this value be archived before all the bitcoins are mined?

When I buy bitcoin someone will take my dollars.
So how can we technically replace all dollars with the bitcoins?
In the end will there always be someone with only dollars in their pockets or  am i wrong?

I believe that based on todays status of bitcoin it is really unstoppable and it can really make us profitable each day but the that is why no one can really get over it and many people have interest on it .therefore i conclude that bitcoin is unstoppable each and everyday it is rising and its heat of profit is verry hot the opportinity is really clear and it is verry safe .

We can say, bitcoin is much better in terms of investment return but we can't say that it could be better for a long term investment. Just because of bitcoin's price  volatility compared to real estate and stock. Though they have also chances of price inflation anytime but it is only of less percentage compared to bitcoin.

Yeah, we cant predict exactly when will the bitcoin price drop with that amount but i think in the current status of btc its unlikely to happen. Even recently there are some coins increasing (bch in particular) the price of bitcoin remain around 5k$-6k$ and now its back on track again and continue increasing as day passes. Investors already know that btc price can crash or skyrockets, so op dont need to remind everyone for the possible situation that can occur.

I think last week was a lot different as people were panic selling and some fell for the BCH propaganda...
Plus, the mempool was a disaster

This weekend all in all I think BTC is doing well, some people still trying to speculate, but don't think we will see any major drop; last week by now it was already pretty high

The important thing is to make an investment according to ourselves before it's too late, but I think BtC has reached the peak, so it will not be as profitable as the old one.

Baka may nalabag ng rules yung kaibigan mo. Nagdedeactivate ng account ang coins pag galing sa gambling yung pera na dumating sa coins nya. May kaibigan din ako na deactivate ang account sa coins dahil galing sa gambling yung pera nya. Ang masaklap pa don hindi na binalik ng coins yung pera nya

Bitcoin is definitely safer, but some altcoins may provide higher short term returns, but I think it's not worth the effort to keep up to date on all altcoins so that it is worth to invest in a bunch of altcoins.

if your problem is your cheap salary  its better to invest in what you can afford in bitcoin..if you have time in trading to your work and you need to have income to increase your profit in a month just give a time for trading that cant affect to your job. and invest in the half of your salary to get more profit..

You should keep holding now until bitcoin reaches 8000$ for real. Sell it only a portion after 8000$ price has been achieved and hodl the rest. That way you would not have to fell regretful when price goes down and you also won't regret selling early when it goes up more. Anyhow, it would be wiser to diversify your money on many different cryptocurrencies for more profit here in crypto world. Bitcoin is not the only crypto with potential so learn how to pick good coins with potential before doing this.

Until the day that bitcoin is the only globally accepted currency, and by that I mean the only currency in the world, then of course the price will matter. Frankly I don't think that day will come and so for me the price will always matter if I own some bitcoin. I would own bitcoin with the hope of growing my dollar amount.
