Am not much familiar with cryptocurrency, and that's why I need more guidance so that if eventual I see one, I will know how to handle it, this will help me to have a good knowledge on the path to settle for.
I am always careful when I see coins that the creators engage in massive advertisements. When huge funds are spent to promote a coin, it's a red flag for me. Any coin that is hyped by celebrities is not also for me. I see these actions as a means to attract people. A coin should grow generically and not attain a high price overnight. Coins that come with guaranteed and huge profit looks suspicious. You will not get a black-and-white answer OP because the crypto space is complex and unpredictable.
It all depends on your goals for venturing into the crypto space. If you want a long-term investment, Bitcoin remains the best. But if you want to engage in trading and make fast returns, consider altcoins. Always remember that trading needs some skills and is risky.
