You have to use driver.execute_script()
with JS to modify the DOM.
count = len(driver.find_elements_by_class_name('coinlist'))
for x in range(count):
x += 1
flip = driver.find_element_by_xpath(f"//ul[@class='coinlist']/div[{str(x)}]")
driver.execute_script("arguments[0].setAttribute('style','visibility:hidden;');", flip)
