Hello im a 36 year old union electrician from Knoxville, Tennessee and i am all for Bitcoin ETF's, i really believe they would be beneficial for other electricians who have worked extremely hard to have a decent retirement plan, Bitcoin ETF's would mean that my retirement plan could invest in Bitcoin, which is a extremely valuable commodity in my opinion, anything that hasnt been hacked in over 9 years and will only ever be 21 million, (probably 17 million with 4 million in lost private keys that will never be recovered) with that type of scarcity it could help me and many others in my field who have sweat and bled for over 30 years in the electrical field to have a decent happy retirement with their family.

Thank you
