In this bear market, does 100$ on Ethereum or Bitcoin make any difference? As a newbie who have only 100$ to risk is this even enough? Can this get me anywhere?
It depends on how much profit you are looking $100 can go a long way if you can be patient enough to hodl for a long term on Bitcoin. Altcoins could be risky and manipulative. As a newbie applying risk management by sticking to a single project that has long term goals just like bitcoin will save you the implication of pump and dump projects
