are you okay with trading precious metals? stocks? real estate?
all of those have so-called market cycles, which is what you described here. the price continues to increase (bull market), as each trader sells higher to another sucker, who wants to sell higher to another sucker... until eventually it runs out of new suckers and the price collapses for some time (bear market). each dollar you gain is a dollar someone else loses. those suckers at the end of the bullrun transfered their money to earlier suckers and lost everything.
the "ponzi" nature of crypto isnt specific to crypto at all - this is how all markets operate.
