Don't worry, you can get long time hold with your bitcoin . because bitcoin will be again get up . then you get more profitable. So it's time to just holding.

Every investment has a risk but bitcoin is long tram business, no one sure bitcoin gain a profit

Bitcoin investment has so much risk because once and for all, bitcoin is money. Bitcoin is a paperless money.
So in investing in bitcoin, you have to be wise and see to it that you have done your research. In the traditional way, it's like making a feasibility study.

yep you have risk. You have risk in all the currency related trading or investment, but for bitcoin there's no risk involved but patience is required to wait till the prices are up and should not get panic in between. To be specific bitcoin is 0% risk but 200% profit, this is just for one year and if you invest for few years the profit doubles or triples your actual investment amount.

Nothing comes without risk, especially when it comes to any form of currency whether that be fiat or crypto. When judging whether or not this is a worth while investment there are several things that bitcoin offers that make it unique and imo a worthwhile consideration. Bitcoin and the system behind bitcoin uses encryption techniques to regulate the amount of the BTC generated this is a positive as it prevents any mass market manipulation, do people want it? I think from what we have seen over the past few months and years it is clearly an asset that is increasing in demand and yes don't get me wrong past performance is no guarantee of future performance however it is usually a very good indicator. With the amount of press currently surrounding the subject and the drastic increase in traffic imo it is a worth while investment.

I have seen this question many times and i will continue to answer it the way I usually do. Every investment out there is not 100% safe. If you invested in gold and thought it was safe, think again, the government could seize it like in the great depression. What about leaving your money in the bank, the bank may go bankrupt and you wouldn’t get your money back. Thinking about investing in the stock market, the whole thing could crash the next day. Same with bitcoin, no investment will be 100% safe and have profit, that is just too good to be true.
 
Even though with these risks, I would still invest in bitcoin since it seems to be a good option out there and it seems to be on a steady rise up. But, don’t put all your eggs in one basket. Diversify your portfolio. Have some money in everything. This, in my opinion is the safest investment option.

 The risk of coin market is not certain at any time . You should be patient to earn Money from BTC. It can decrase 1000 dolar or it can increase 20.000 dolar you have wait to earn Money.

investing in bitcoin involves very high risk the prices of bitcoin extremely fluctuating but if you want high return there is a high risk in investment in bitcoin but bitcoin is very profitable for the future.

At a very basic level, there are two obvious sources of risk:
High volatility by definition makes bitcoin risky. A popular cross-rate XBT:USD has a realized 30-day volatility of 43.3% and a 90-day volatility of 67.44%. Not many people can stomach the swings you see in Bitcoin's value.
Security risks. Given the relative infancy of all parties involved in the act of investing in Bitcoin (exchanges, escrows, wallets), the security protocols, interfaces and code, etc. are ripe for attacking from a hacker's point of view. These vulnerabilities have been and are being exposed and exploited fairly regularly. See Mt. Gox, SilkRoad, etc for evidence of this in action.
I'm sure there are many other nuances and more involved risks embedded in a purely digital distributed currency, but for purposes of the average beginner investor, the above two should represent the bulk of "risk" experienced

agree with your opinion when you choose the investment we have to learn it does not necessarily immediately invest. it's all a matter of loss and risk that's what every time people suggest before making a decision
