So crypto is new to me. The concept of the blockchain and wallets can be confusing at times. I had no idea where to start in buying crypto in order to buy DEC/SPS. I experimented with Coinbase and if you read further, you'll discover how to get free crypto in order to buy DEC and/or SPS.
If you go to Coinbase and create an account, you're given the opportunity to earn free crypto, that's not mainstream crypto, if you watch videos on the free crypto. I was able to get $3 in one crypto and $3 in another. Once obtained, you can transfer it to any of the mainstream cryptos if you want. In order to buy/sell/send/receive crypto, you have to confirm your identity with Coinbase. After you have your crypto of choice, then you must send it to your Coinbase wallet, which is actually an app on the app store. Once received in your Coinbase wallet, you can send it to the HiveEngine.
Once your crypto is in your Coinbase wallet, go to the HiveEngine, click on wallet and then click on deposit. Choose the crypto you'll be depositing from your Coinbase wallet and then copy the address of the HiveEngine wallet you're given. Go back to your Coinbase wallet and paste the HiveEngine wallet address into the sending section to send the crypto to HiveEngine. Once you send your crypto to HiveEngine from your Coinbase wallet, you have to sell this crypto to receive Hive tokens. To do this, click on the crypto you currently hold in the Market section. Scroll down to the selling section on the right and enter the amount you have to sell and then enter the lowest bidding sell price, which can be found in small font just below the sell section. Next, you'll click the sell button to get Hive tokens. Once you have Hive tokens, you can buy DEC or SPS.
Next, go to Splinterlands and click on the DEC icon at the top. Click on the wallet you want to import from and send to Splinterlands the amount of DEC that you have on the HiveEngine. For SPS, click on the SPS icon at the top and enter the amount of Hive you have in order to transfer it to SPS.
Now you have free DEC and/or SPS!!! Wish yall the best! It worked for me and I hope it works for you!
