Yeah, bitcoin is trustworthy, but I think you should alter your post to include a question mark. However, I believe you still do not understand the main purpose for which bitcoin was created; you must first learn everything about it; it is not like other platforms that you have tried and failed because they promise big profits; bitcoin was created primarily for transactions, not investment; it is only now that investment has been introduced in order for it to be more widely adopted around the world. In my opinion.
So I believe you should learn more about it and trust it if you are willing to take the risk involved, so you don't need to be eager there are things you need to learn before investing in btc maybe you didn't do much investigation about those platforms that you did and failed, so here you need to do more research about it and be asking questions in the forum.
