Retirement fund (hopefully)

Hey guys! Been lurking a while now til I got on my feet and managed to get a sustainable job with a small disposable income. I’m looking to start a small monthly investment of around $50 per month into ETH to maybe retire one day? I’ve been beyond broke for a while now and finally exited to start investing and seeing wealth grow. Never seen double digits available to spend for a while now so I’m pretty excited!

Let me know your thoughts please as I’m new to all this crypto stuff and don’t have a lot of money to waste if it’s a bad choice!

Thanks!!
