Those who invested in bitcoin way back 2009 had not experienced any bull run before nor have much knowledge about the blockchain technology, yet they took the risk to invest. You and I have witnessed a bull run and heard about the numerous potentials of crypto so why do we still have to feel reluctant to invest in bitcoin. Let's be optimistic about our digital assets because its all we have.
We all have to give trust before we gain profit,just like what those first investors did
OP is right that they didnt even know the word BullRun back then yet they put money to the technology that has nothing proven,not until now that we all seen the capacity of cryptocurrency
Lets make this as stepping stone for the goodness of us all,invest now when the value is still cheaper because sooner for sure bull will come to bring us fortune again
