The project you invest in, will determine if it is a high risk investment with high return, a high risk investment with a low return (or no return), a low risk investment with a high return or a low risk investment with a no return; it all depends on the project.
Bitcoin, Ethereum, and Binance coins for example are low risk investment with high return, but this high return will depend on if you are willing to hold for long, and considering most people who invest in them are long term holders makes it interesting for them.
The high risk with high return can also turn to high risk with no return at all, which have been seen in new projects which are only following the hype, they just list and exit scam within a short time.
So before you consider buying or investing in any coin or token, make sure to understand the coin and know the potential risks involved, this will help to protect your investment in that coin; most people only stick to already trading coins with good team while others prefer to try their luck with every new tokens just getting started with the idea of entering early and getting out quick.
