Unless a coin (each looked at seperately) develops to the point that it is used without the need to go through BTC, things won't change much.
Which coin has a purpose, IF it has a real life purpose, is up to you to decide (my SUBJECTIVE view is that atleast 90% have 0 real purpose).
Because, again IMHO, only those that have real life purpose (other than "we can buy stuff with it") are truly worth hodling.
But that's just me.
Oh, and...when you invest subjectively small enough amounts, just like if you go out and buy 5 drinks and forget about it, you will NOT react to ANY price change, because you invested what you consider lost already and you have faith in the technology/plans of a certain coin you invested in.
EDIT: I have 5 different coins, 1 main and 4 "shitcoins" in who I don't expect nothing really
I bought almost 2 years ago and haven't felt sad at ANY point, even though all coins were like 1000% higher than now.
I invested a small amount and I don't care. Main coin is far from it's potential and the rest...if it happens, happens.
I truly believe when you make correct steps, you don't react to anything and keep a sane mind.
