How much to buy in with?

Im new to craps and have only played 2-3 times after watching HOURS of craps content on youtube. The last time i went my dad came with me and i bought in for $300. He told me that wasnt enough for a $15 min table but he himself doesnt really gamble and probably hasnt played craps in over 5-10 years. I did proceed to lose $200 over probably 4-5 rolls. How much should i be buying in for at a $15 table if im playing the pass line and place bets?
