Need a demo account for a crypto base account currency exchange so I can fine tune my API skills without " just throw 25 dollars its not going to kill you" stupidity.

No exchanges offer demo accounts? WTH
"just throw 10 dollars away " or "get a faucet" type BS only?

Also noticed all crypto exchanges' support that I have been serially contacting for info about minimums etc really blows. They wont answer emails and they dont offer live chat under the cover of "we aint big enough" apparently.

No crypto demo accounts to fine tune API skills ??

PS . Please no status quo paladins defending their mediocrity like robots after this post k thx
