Investing in Bitcoin is risky and it really makes us lose money if it gets too high. And many traders are too selfish because when prices go high they see the profits they can get so they sell all of their Bitcoin that causes prices to go down.

Bitcoin is approximately as dangerous as carrying around cash in a wallet. If you lose the wallet, or it gets stolen, then your money is probably gone. This is analogous to having your private keys or seed phrase stolen (although this is much more difficult than stealing your cash wallet). If you don't take the time to adequately understand what you're dealing with, you may end up victim to a scam, similar to how telemarketers pray on the unknowing.

Simply this, take your time, understand how the technology works, learn how to protect your assets, and then invest.

Why are you saying investing in Bitcoin is dangerous?) IMO, let's say investing in Bitcoin is risky. The fact that the Bitcoin exchange rate has been decreasing recently has led to a gradual decline in investment in Bitcoin and more investment in altcoins in the early part of 2018. But I still believe the BTC rate will increase sharply. Expected to exceed $20,000 by the end of 2018

Yes, investing in BTC has some risks. But risks cannot be avoided in all investment. That is why you have to research before investing in any investments.

For me it is risky because you don't know if the price is going up and down so if you want to invest in a long term you should wait the bitcoin price if it is higher but now the bitcoin price is higher so it's better to invest now.in fact you have to take a risk for that investment.

Yes it is very dangerous because it has a high volatility, meaning it can rapidly increase or decrease and its very unpredictable in terms of its movement. Due to high demand by mean time, the price starts to hike and when it will happen they will sell their bitcoins and so the price decreases. It is a win or lose situation when you get there, better have datas to study and lots of patience.

true, investing in bitcoin is quite dangerous and at great risk. but not with a scam or ponzi scheme. bitcoin is knowledge, and involves experience. so you should try to find various knowledge about bitcoin and crypto.

No only rumors, risky but not dangerous. Investing in bitcoin is good fortune for us to become financially stable and successful. There are so many people now want to invest in bitcoin cause they know there money is safe and gain a profit.
