Any reason why you want to start your own daemon instead of just using a pool and paying the low 1% fee? I don't know how it is for XMR but with ETH or BTC if you want to mine it needs to be fully synced.
I can't think of anything other than OP is trying to solo mine Monero or opening his own pool.
BTW, Just like Bitcoin and Ethereum, Monero also requires a fully synced node before you can start mining.
Unless he's not informed about mining pools, the only valid reason to mine using a full node is "
solo mining".

here, there are info and links to their sites too if you need more info.
Great post and very useful DYOR link. However, i'd also like to add that when if and when you eventually decide to go mine using a pool, here are some of the popular mining pools:
Each have their own payout schemes and configurations but i'll let you figure that tout.
