im not a usual writer, and usually dont blog, but i cant seem to find this question i've been wondering so many other were as well wondering. From a couple hours of research and i may be wrong, pls do your own research, i'm just blogging this because i see no one else has and would like to let a few others that had this questions as well. first off im pretty sure you can buy RAM from off chaine.com, graymass wallet, and the scatter extension with the eostoolkit, but im not 100%. RAM will actually be the only way anyone will be able to build anything on top of Eos blockchain, and the people need it , common sense is the price will go up as more dapps will be built. The eos blockchain just went live and needs time to grow, so any price for now i believe will be pennies a year or two from now. im sorry for the grammar and lack of writing professional blogs, but i thought like me people wanted to know this info as well.
