There are so many answers which can be alloted to this question, well i can say the best answers among them are:

• firsly, i will o wipl cash out some money coz 100 bucks means alot here in my country and i haven't cashed out any steem till now ,wanna see how steem tastes...
• Secondly , i will invest it in the steem till it reaches more than 1$ coz having your own self vote value like 1$ is achievement in itself.
• Thirdly ,i will cash out the money not for myself but for spreading the word about steemit coz it will benefit me alot and them also.

And yes 100 bucks seems alot but steem has this potential to up like that ,Release of SMT will surely make it go bullish,i am really waiting for the moment.
