Well, yes, every investor must consider many things before carrying on their investment. The factors that you mentioned, such as "capital safety" and "level of profit," are what every investor usually considers, but that's not the only thing to consider while investing your money in any asset. Before investing your money in any asset, always make sure to evaluate all the possible risks that are attached to the investment and ask yourself if it's something that you can handle. Regarding the safety you talked about, if the investor is investing in a centralized platform,it's wise to have an agreement that assures you of your asset protection against liquidation. The reason why I am saying this is because some months ago, I invested in some business, and at the end of the deal, I lost 90% of my capital, and I couldn't ask them to give me back my money in full because we never evaluated the risk and had a proper agreement. So, I just accepted my loss and allowed it to slide; at least I learned my lesson.
