With 4k Bitcoin I assume you mean 4,000 USD invested in Bitcoin. Or do you actually have 4,000 Bitcoins, which would be 112 million USD   Unfortunately there is no guranteed way where you can make profit of 100 USD per day. That is a 2.5% return on your investment every day.  To achieve such high returns you are going to have to take a lot of risks, and the chances are much higher that you are losing money than making money. Nobody can offer you such returns with a guarantee, if anybody tell you otherwise it's like going to be a scam. Why do you want to make such high returns per day? You should be looking for more reasonable returns, like 100 USD per month or 300-400 USD per year. Also most money you are going to make from bitcoins you make by holding them, there aren't really bank accounts where you can deposit your coins to get a fixed % return per day.
