I'm not talking about those ultra big youtuber like pewdiepie etc. whereby they are already deemed as celebrity. (then again, even famous A list celebrity could 1 day go broke)
I'm talking about those Malaysian Youtuber. Especially those under 1mil subs.

Can they actually sustain? Can they do Youtube forever and if not where can they go in the future or perhaps unemployed and broke?

It is not uncommon for Youtuber to just fall cause it happened to some youtuber (not including those intentionally dropped out like kevjumba etc.)

Basically, such channel would be like Peter Chao. He had millions of views last time and is considered one of the big youtuber during his peak but now... his channel rake in less than 20k views for each video. Not sure if he can still sustain even with 800k subscriber but he still makes video and have side gigs.

There are many more but Peter Chao is the only one came to mind. Anyhow, they are westerner youtubers... they tend to somehow have some side gigs cause media and entertainment is still viable is those countries.
In Malaysia however, I do not think there are much opportunity in entertainment apart from youtube.
Hence how would you guys think these Malaysian youtubers will do 10 years down the road?
