Seriously? $100 as profit daily from your 4k Bitcoin investment?
This is not a Bitcoin investment, but you may need to go to trading. But, this is also dangerous for you, moreover, if you are new to this. Investing in Bitcoin needs the patience to gain more profits. With that amount, I don't think you can earn $100 daily from investing only if you re not trading. Even if you are staking or doing others, this will not give you that kind of profit daily. But if trading, you must work harder and harder, buying and selling Bitcoin any time, with high risks, an excellent strategy to analyze the market, and other understanding that leads you to be a professional trader, so you can earn the daily profits that amount or more.

Btw, if you are contacted by someone that said they can help you to gain 100$ daily profits or more, NEVER TRUST THEM. They may be scammers that will scam you with fake investments. Be careful.
