I really see you have been here since 2013! I have to admit my biggest investment is time on Steemit and guess what i have so far accumalated 500SP from zero in my 8 months which is a great return on investment. I have also learned a great deal about crypto especially you(only that of late you reduced on the crypto lessons!).

In short my biggest investment is joining Steemit,through Steemit am also now have a few altcoins.
