It's not a threat, threat is different and far from risk. The right term should be risk and that can be found in all types of investment. Even the very easy investment which is holding has the risk and there's no way to measure those risk, it will only depend on how you can take those risks.

I reply that it's extremely risky investment. It can't be predicted or controlled. Easy to lose everything in a simple moment

the risk will always be on every investment, let alone on bitcoin investment many users consider that fluctuations are the biggest risk in bitcoin but in fact if you can take advantage of fluctuations into profits then the risks in bitcoin will be reduced or even disappeared, for example traders take advantage of fluctuations for their trading activities so they are not too concerned about the risk of fluctuations

if we buy bitcoin in high price then the risk is always high too but if we can get bitcoin when the price is lower like few years ago, then we don't have to worried about the risk. beside we can take big profit because we are still holding until now, we can use only small amount if we want to withdraw just to take our money for investing back plus we can take some profit.

every investments has a risk. but if you dont want to risk tjen just invest little amount. if youre a risky one then you wull have a big profit.. but buy bitcoin or any coin  in low price so that it has a low risk.

There are risk in every investment that you make, even those that are very low risk, like an investment in the US bonds, has a risk that the US is not going to pay you, so investments have risks associated with them and the the longer you deny that fact then your ability as an investor will be impaired.

I'll take one question at a time. Let's start with the question "Can bitcoin price decrease?". The answer for that is YES, bitcoin might fall at any time. There's always a risk on investment, and bitcoin is no different at all. Since bitcoin is known for its volatility, we can't ignore the fact that at any time, your money might suffer a lot. Don't worry, anyway, because bitcoin has gone through a lot of situations like this, but in the end, it was still able to recover.

Now, let's take the question "Is this the right time to buy bitcoin?". That depends on your plan. If you plan to invest your money on bitcoin for just a short time, then I think it is not the best time to do that. Short-term investments usually don't succeed due to the fact that the movement of transactions in the market is not done in just a month or two. But if you're investing for a long-term, then I think it is still a good time to buy bitcoin. Who knows, bitcoin might double next year. Tracing the track of its value's growth, we can see that bitcoin has indeed grew to become one of the BIG THING in this new era.

if you are thinking about risk of investment in bitcoin then you are not doing investment just time pass because bitcoin always gives profit with long investment. this is true there is up and down in the market and some time our investment show low or decreasing balance. but if you want big don't think short its rule.invest in bitcoin and earn money for future.

I don't consider that there is even slightest risk in investing in Bitcoin if you invest for a lengthy time as Bitcoin is displaying quite healthful prices of progress and you can be confident that you will earn good earnings if you wait around for some time. Brief term investments in Bitcoin cannons a minor risky.
