Bitcoin is decentralized so pump and dump is common, before we invest bitcoin then the first thing we must understand is the type of investment, bitcoin is a high risk investment type so if we are not ready to lose then we will be crazy, but the fact that I experienced is has never lost when buy bitcoin with a note must be patient to wait for get the best price.
Yeah, we have the same thought. Pump and dump are just a normal things. But surely, when the price is down, it will up again immediately.
That's because Bitcoin will always be use by people and will not get beaten by other cryptos. I think Bitcoin investment is not high risk.
It's just need a lot of time to make some real profit. Not just weeks or months, but years. But, the investment can also have some risk.
That's because we do not know yet about the Bitcoin future. Maybe the developer will get more creative and smarter to improve the system.
