Never late to start and in fact I think this is a good time as Chaos cards are by far stronger than past series while general sale of the packs may lower the buy in cost of the cards too. This is a good time to invest in the game and grow.
After some years in the crypto space I have found the true key to success is finding projects where there is a strong community. Splinterlands has that and with Hive it goes beyond just the game. Best of luck on your journey in the crypto space.
