never Invest in everything that you don't understand , you are a newbie in crypto yet wanted to risk investing ?
if you are talking about a trial amount then you can put small funds towards Ethereum but i'm telling you best that you are ready for what to come your way because trust me this is not easy market.
and also never listen to other people because this is your money and if you lose , there is no other that will suffer but you.
Let us face it though,,, most people entered into crypto without really understanding anything. If people invested in stocks on Robinhood and Forex on eToro did not even realize what they were doing,,, why would it be so different for crypto people?

And maybe it is a good idea to suffer first. Then you know?

Not really necessary for you to suffer first but most of the time this had been the situation on where people do really end up.They would really be minding when they had been slapped out by the reality when it comes to crypto investment.
Its actually hard to determine on where could price will go even its on top ranks then presuming out on where its peak price would be always in question and this is where risk management factors does really matter on each trader or investor.
If you do really believe on ETH potential then its up to your choice but of course you should mind off the risk.
