You’re welcome OP. I’ll start by saying that no one is an island and we’re all here to learn and relearn which requires us to also make mistakes. ”Is Bitcoin trustworthy?” should be your topic. Also, this is a vast community/forum which most most basic questions have been answered. I’ll suggest you start by going over the forum and I bet you’ll find the basics of what you’re looking for and will reduce your worries.
Nevertheless, Bitcoin can be viewed as trustworthy due to its decentralized nature. What does this mean? It means that bitcoin is not operational or controlled by any government, bank or organization. But this doesn’t change the fact that it is risky cuz just like any other financial market bitcoin is also volatile, which means it price can fluctuates. It is also important to note that there have been instances of fraud, hacking, and scams in the Bitcoin and cryptocurrency space at large, this is why one need to have an in-depth knowledge about bitcoin and cryptocurrency to be able to securely invest and trade the space without any fears.


I urge you to make use of the "Beginners and Help" forum to further enhance your understanding on Bitcoin.
