Hi, everyone. let's assume I have $100 I can afford to lose, what can I trade more profitable, bitcoin or ethereum and other relatively stable altcoins?
when you want huge profit then you shouldn't be looking for stability!!! you should instead look for massive "upwards" movement or a big rise or as we call it a pump.
many altcoins are like this, but the question you should be asking yourself is that which is like this "now". then if you found such coin, invest in it and get the big profit.
you invest in bitcoin for a long term investment because it is a solid one and will give you profit in long term for sure. that is not true for any of the altcoins including eth.
as I understand I need to pay big transaction fees every time I trade bitcoin, am I rigth?
no, the trading fees are the same on the same platform. I don't know any exchange that charges different trading fee on different markets!!
