What is the reason for the large fluctuations of altcoins in your view? Why are altcoins so fragile compared to Bitcoin and fluctuating with the smallest news? Of course, I mean the altcoins that have good ideas, professional support,... not the shitcoins.
One of the major reason i believe is the total reliance on Bitcoin, Most altcoins are usually trade paired to btc.
Which is why sometimes, when bitcoin dumps 10%, certain altcoins dump 100%
and even on rare occasions, if bitcoin moon 20%, some altcoins dip 200%, it has to do with the sats of the buy orders too.
Why not try trading and practise with 5$-10$ see what you can do ?
Just my views though, do your own research and have a better understand
