The amount of risk investing in altcoins should be enough, don't go beyond it because I am sure you will regret it. That's all base on experience and I am just sharing the outcome.
Ethereum is known as one of the tops in the altcoin industry, if you check its price chart you can see how far it has already come from just single digits to now 4 digits. But that means long-term investing, if you are aiming short-term then the trading discussions might best fit your need.
Don't forget that it all depends on the duration of the investment and on the amount invested. When we talk about investing in Ethereum, we constantly remember that it grows very well and that it is very well-known and unlikely to turn into a scam. But at the same time, we forget that it is already a rather mature asset, which has grown a lot from its original price and no longer yields interest to its investors so briskly. So it doesn't make sense to invest in Ethereum for a few years if you have $500-1000. It's like investing in gold with $10,000. It's a good option for preserving value, it's not for making money. So investing in assets like Ethereum makes sense when you have enough money, but in no way a couple of hundred dollars and not when you are an absolute beginner.
