just keep spending for weeks, and slowly increase your daily budget it will definitely break the $50 barrier, otherwise if you want a quick solution then verify your business and get the limit removed but its a hectic process because you will have to provide them tons of docs and wait till they approve or deny your request
Another way I know is to contact them in advertising chat support it helped me to lift the $50 limit but its not a reliable practice again because they will lift the limit of 1/10 accounts in this way.
