Adding on to that I would say as a newbie invest more and more in education like there are ample of online websites where you can learn about cryptos and last get yourself a broker. There are many brokers like Coinexx, FX choice or LMFX who offer good trading conditions. Selecting a good broker with good conditions will help you trade better.
Newbies shouldnt start to trade with big amount, i prefer small amount for the practice purposes. Newbies firstly more possibility to losing money in shrot time, so no need big capital at first. Brokers i think you mean exchanges, those arent reliable and known in crypto space which you recommended. Conditions dosen't fact, as a newbie you need a lot of practices at any condition.
And also there are practice for free in other exchange now so newbies dont really need to spend a single amount to start learning.
but of course traders need to Lose at first to be more functional and assuring every trades they do and this is what we need to be specific in trading,Losing is part of this profiteering and never expect 100% success.
