Actually, you can say this about other altcoins, which are basically cryptocurrencies, but I don't think it would apply to Bitcoin. Bitcoin is under the crypto coin but its purpose and network is fully decentralized which is actually not possible for anyone to manipulate or control. Yes, it is true that sometimes bitcoin is manipulated but it can never be sustained for a long time. Now if we consider bitcoin only as a trading asset then maybe we may face losses while trading but it cannot actually erase its main purpose.
But if you truly believe in it as a virtual asset and adopt it for the long term, you will inevitably realize that bitcoin is truly decentralized and not under anyone's control. It will never be possible to understand this by trading short time if he is a beginner.
