Ive been using bitcoin since 2011ish i think, one of the first few people on bitcoin-otc first trade was $40 for 10 bitcoins (paid with paypal transfer funily enough) i must have bought and sold hundreds over years, still have few dozen

In some cases yeh bitcoin has not lived up to initial promises, literally first line of satoshis paper is no longer valid, but it could yet be like early internet and take off (or something similar)

i wouldnt write it off but yeh you are also right its not what we thought it be, the whole store of value thing these days instead of currency
