i think everything has its own negative effect on the society, bitcoin is the case too, because of its anonymous platform making no one can control it so criminals has used it as a good tools to active and easily high away from governments, this is a serious problem that can hardly be solved by governments and surely takes a very long time.

this is a normal to me because bitcoin is getting more and more attention from the public, and get more interest from them due to its high price and a good chance to be rich by just investing in bitcoin for longterm, but this also makes  the price get higher that many investors can afford with high quantity.

in the next year, altcoin will surely rise very much compared to this year, i believe it will reach 1500$ at the end of the year 2018. i think more and more people will get involve in investing ethereum because no one can deny the benefits that eth can bring to us, even better than the other coins, so its potential to rise higher than 1000$ is possible in next year.

i guess this happen because of the pumping of many big investors who have huge amount of bitcoin, they want to get much more profit so they buy a large amount of bitcoin, making the price of bitcoin rise up so quickly, more and more investors buy bitcoin will make its price higher, and when big investors sell, bitcoin price will surely drop.

no, i dont think it will reach 15000$ so easy in just one month, bitcoin is rising now but it is very fluctuative that we can never guess exactly what will happen to bitcoin price in next month, but i really hope not thing is impossible so as long as it keep rising it will always bring me profit.

i think dash can be able to pass bitcoin in the future, not thing is impossible, but it will take a very long time for dash to have its chance to rise and develope because bitcoin is the center of all investors concern, so it will take a little for dash to be popularized by all investors.

nowadays it is very hard for us to get profit from ICOs because many ico nowadays is scam or they collected low fund, so they dont left their investors or just pay some coins for no value at all. moreover, invest in ico need a long term investments, we can only hold them and wait until it rise in the future.

as a bitcoin holder i always affraid bitcoin price with drop down below 4000$ that is the day i will have too make a decision whether to cut lost by selling it or still keeping bitcoin. also i affraid bitcoin will be banned by all countries and be replaced by an altcoin that can be better than bitcoin.

i really dont hope bitcoin will reach 15000$ this bubble is getting too big that nearly reach its limit and may be blow someday in the future and drop back to its real value so that i can have a chance to buy bitcoin with cheap price. but this can be really hard to become true because we still not know when will the big whales dump bitcoin.

looking at the chart of bitcoin price, we can see bitcoin is just more than 1000$ in first day of 2017, but until recently bitcoin rocket to 9000$ in just few months, perhaps the appearences of many hard fork creating new coins to against bitcoin, but they just make bitcoin stronger because they are not trust worthy to investors, so they put their money in bitcoin more and more making it become the highest value and strongest coin on the market.

i think there are so many ico nowadays making us harder to distinguish which one is scam, so we should do research carefully to protect ourself first, make research about their whitepaper, roadmap, and their advisors, if these things is not cleary or fake, then that is scam, or you must check for interactions between investors and their advisors, they sometimes dont have clearly answers for our question and check the review websites.

i really dont think owning too much bitcoin is greedy, it is our right to earn as much as money we can to better ourlife, so as soon as we see bitcoin has the rising trend we take the chance and hold bitcoin as long as we can to earn much more profit, i do believe bitcoin will keep rising in the future so i wont easily sell my bitcoin without earning any profit from it.

Bitcoin die wont lead to the result altcoins die, altcoins are born to be better than bitcoin at many ways, so if bitcoin died the world will be very shock, and may be the whole cryptocurrency will be effected badly by bitcoin dead.

there are so many governments have banned bitcoin, because they still not be able to find a ways to control bitcoin, it is anonymmous so it makes governments harder to trace and charge taxes on Bitcoin.

i think there are many ways to detect an ico scam, you can read on their website if their project dont have enough information about their whitepaper, roadmap, and their coin infromation, or you can look for assessments from ico reiviewers. however i can guarantee no ico project is safe no matter how much you did research on it, so it always up to you, whether to take that risk or not.

i think the concept safe and profitable are very opposite to each other, how can you earn much money if you dont want to take any risks, choosing a safe way is good but having brave and invest in somethings risky like bitcoin can bring you so much profit, so if you want a safer way you can choose investing in altcoins.

i think there no one can destroy bitcoin unless they can shut down entire internet network all in the same time, so this can hardly happen, bitcoin use internet for its currency, so unless there somethings wrong happen to human kind, bitcoin will never die, or in a very far future, all investors dont want to use bitcoin anymore because bitcoin has been obsoleted, so they will use another coin to replace bitcoin.

this is a good time to invest in bitcoin because rightnow, bitcoin is rising very much compared to few days ago, if you can invest in bitcoin soon you can have a great chance to sell at its peak for big profit, and furthermore, bitcoin is a good investement because it has been popular to our community so much, and the first coin on internet bring many benefits than normal fiat money.

Bitcoin price now is very high, and it could rise more in this year, so i think it is not too late to buy some bitcoin now, the profit may not much now but i am sure in the future bitcoin will bring you very high profit.

Bitcoin will survive for every long time as long as many people use bitcoin, but until today i have realize bitcoin has many disadvantages like small blocks and delay transactions that can threaten entire bitcoin life because investors need cryptocurrencies fast, secure and no delay, so bitcoin wont last for if it does not change itself.
