Please help clear cc strategy out

Hi all, I am new to cc trades so hope someone will help me clear some thoughts before i go all into cc. We all know market goes up, down, sideways,

Assuming i buy 1000 shares of nvda, as today its $188, immediately i sale next week for premium of $4, (strike is not important), in up market its easy to make money its just stock purchase price + premium. But In down or sideway market if i keep selling calls for $4 premium regardless stock price and strike, eventually don't i get the stock for free? My calculation is $4 per week so 188/4 after around a year i will bring the purchase price down to 0, the only thin have to worry is if nvidia won't go bankrupt or delist. If i get assigned before options expire i will repurchase the stock back and keep doing $4 per week options. Please let me know is there anything i missing
