... satoshi instead
(click-bait master) 
today someone came to me saying how he was regretting not listening to me and investing in bitcoin. apparently he checked the price this morning

and he continued that now it is too late since he can not buy 1 whole bitcoin.
i had to sit him down and have the "talk" with him about all the 8 more zeros that come after the 1 whole bitcoin and the fact that he can choose (almost) any of them and put a number and buy there.
that is why i think it is time to start using the smaller units for bitcoin more often.
i myself prefer Satoshi over all. but there are a lot of them.
