I'm confused, why do you mean that you don't have much? Do you have the capital to invest or not?

If you have money but you can't afford it to invest on ETH or any other crypto then I would advise you not to do it then. I mean you should only invest what you can afford to lose in the market. Specially in altcoins wherein it is very volatile. One day the price could go down hard and you might lost big money. So you have to think hard if you are willing to take the risk in crypto investing.
