Be careful. I overlooked the transaction fees, resulting in a deduction where Bitcoin charged $8.43 as a fee for the shared plan. Consequently, I didn't receive my plan and initially suspected a scam. However, two days later, Helium contacted me to explain that my payment was under the required amount and offered either to cover the shortfall or refund my payment back. After settling the outstanding fees, my plan was activated. Better avoid Bitcoin as payment because of very high fees I'm giving a rating of four stars due to the underpayment issue, but I would like to commend Helium with five stars for their proactive communication and support in resolving the matter in my favor.
