I don't investing any cash entering my hand even if bitcoin is going down or up, I still prefer it to others. I have seen a lot of testimonies of bitcoin despite the challenges it has faced but still good to mingle our mind with bitcoin lifestyle and love it, advertise it, campaign hard for it and trade cautiously. Bitcoin have touches lives my won't be exemption, I must learn, grow and earn from it.
How exactly do you want to take this opportunity to the next level if you are not willing to invest any cash in it yourself? You want to prefer or refer it to others but don't want to invest any cash yourself, that isn't making much sense to me. Bitcoin can surely be a good investment if you can time the market correctly and buy at the right time and then keep holding until you get your desired profits.
It has surely changed the life of a lot of people who heard and believed in it in its early days and never dumped their stash until today or when it hit its all-time high and reached $69k, those were some very lucky people for sure.
