Please cleare $4k or 4k Bitcoin. I think you told $4k worth of Bitcoin. Because you want to profit daily $100. I think there has no another legal way to make $100 profit dsily. Here some some way to make profit daily but thats rate very low. Like staking, farming etc. I think all investment are uncertain. Profit and loss are very close. Any time anyone will happe. So you have to invest here very carefully.
