Hey Semisol (nprofile…u7te) If I created a transaction And it hasn't confirmed yet And then a second transaction I sent that also is not confirmed but includes the coins from the first transaction.... If I speed up The transaction on the first one, will the second one fail because it's a double spend? is that a way I can save it????
