I think that one should do quite a comprehensive study before investing as there are so many good projects and not so much money. My advice is that you should invest in coins that are listed on great exchanges, as they do quite a bit of research before signing a coin.
Research is a must before buying any coins. Whatever the amount of money we have, don't hurry to buy without deep analysis.
You are right that the coins listed on established or reputable exchanges are the priority. If the coins are listed on the exchanges like Binance, it means the developers or teams have good quality and they are serious to run the projects. Binance won't accept bad coins to list, they have some standards. And the developers must pay big money to list on exchanges. Only a serious project to list the tokens there.
I agree with this. One must thoroughly research first before making any kind of investment. An in depth research must be done to ensure that your money won't go to waste. Deciding impulsively could cost you big time. Because maybe instead of profiting, you'll end up losing if you're not knowledgeable enough about what you are planning to enter. Risk assessment is a must and so is risk management.
If you plan to invest in other cryptocurrency aside from bitcoin, make sure to check the developers background as well as their project paper. This is to safeguard your asset in case you plan to really invest on it. There are many coins that are being hyped only to find it crashing afterwards. Anyone must be wary of shilling. Do not be so fearful and greedy when it comes to investing.
