There is no mining website out there, what's left are online mining calculators e.g whattomine  and mining pool like Nicehash and others, if anyone ever told you about a website where you can mine with no miner e.g asic Miner or gpu it's a scam they are running, it's better to close such website and look for legit way of mining Bitcoin and altcoins.

Find money and buy asic miners like s19 but first check your power bill, if it's costly or not, because many people did this mistake and they end up selling the asic miner back for a lower price.
