I still dont try it on real play because the bonus buy amount is high while the volatility is high too.

Yes, I do this sometimes but I dont feel changing currency because I dont like guessing how much is my bet and profit while its inconvenient to do manual convert while playing just to determine the value in that currency.
But I do change currencies when I have limited funds coming from my bonuses so that I can still enjoy bonus buy. I only use IDR so far.
Whats the currency that gives the lowest bonus buy?
That's the challenge or the difficulty when we change the currency in order to get lower minimum bet but we are not familiar with the currency.
Of course it is not that hard to learn and make us familiar with it but we are just too lazy to do it, am I right?
This is on the spot. Im too lazy to check everything even a simple thing as conversion since my mind is on relaxing mode when gambling. Its a hassle for me to think on minor details and at the same time being relax.

As far as I know, VND (Vietnamese Dong) or ARS (Argentina Peso) are the currencies that will give you the possibility to play with the lowest minimum bet but Hunt3r may know about it better as it seems that he explores about it more than most of us.
VND seems like familiar to because I work on Vietnamese project before which they are paying me in VND quantity.

Yeah that's what I mean, I changed the currency just to try the sensation of the new games if the experience is impressive I will play again with normal bets

As I said before it depends on the game provider you are playing, for Pragmatic provider VND (Vietnamese) is one of the lowest for Hacksaw Gaming ARS (Argentine) and for Play'nGO or Titan Gaming CLP (Chile) also the lowest. All based on my experience and observations yeah maybe there are other options that I haven't tried. Oh yeah I'm a bit annoyed since 95% of Relax Gaming games are not available in my region even though this provider is in my top 5 favorites list.
Noted on this mate, I will make a copy of this info and bookmark your post as reference if someone will ask this.
Thanks.
