Investment is better and safer than trading and if you invest in the safest cryptocurrency, Bitcoin, you will have a profit. If you invest in altcoins, I am not sure about how you end with them. Most altcoins will bring losses to you, not profit because most altcoins die with time.
Be it trading or investment in crypto, all involve risk and there is no guarantee that the coin you buy or project that you invested in today will be there tomorrow without going bankrupt or even going rugpool tomorrow. Looking at Luna and FTX projects that collapsed taught us great lessons, except when we talk about investment minimal risk we can talk about Bitcoin. People can trade and make their capital today and can also lose the same capital today verse Versa, It really depends on the one that works for you go for it.
