I am currently doing a course on NEAR on a site called dacade.org In the tutorial, after creating a top level account on the NEAR testnet, I create a sub account.
$ near create-account contract.xxx.testnet --masterAccount xxx.testnet
When I do this, it returns an error that my balance is insufficient.
An error occured
Error: Sender yukasaito.testnet does not have enough balance 9.99991607015 for operation costing 100.0000861846776875
The first amount given by testnet to the top level account is 10NEAR.
On the other hand, I am told that I need 100.0000861846776875 NEAR to create the sub-account.
Is the only way to prepare the balance by creating multiple top level accounts?
I would like to know if there is any other better way. Thank you.
