Can I invest $100 in Bitcoin?

i believe yes! Because with 100 dollars u can buy a part of 1 bitcoin, and this money will grou up like the bitcoin grow

Minimal part to buy I think about 1e-8 BTC

It's in 1000 times lower than average comission of transaction

I'm sure you can buy about 0.005 btc with you 100 bucks

sure you can and it would not be a lot lost about the transfer fee.

If it's 2013, $100 is a very very very good invest, if you didn't give up and hold the coin until now. But $100 almost means nothing for current market.

Sorry for my poor English, hope you can understand what i said.

You should wait until the time is right

IE: wait until the market drops to a certain ammount forsay $5000-$8000 and then you would invest , in that situation you would want to put your money in because the outcome would usually be greater. You gotta wait until the value of the coin goes up in order to get your moneys worth of investing.

yeah I agree wait and it will go down some overtime

sure, you can buy so much as you can and maybe getting richer

you can invest any amount but dont expect to get rich overnight with $100 or $1000s for that matter

where is the best place to buy? interested in these

you sure can, i suggest investing a little, whatever you can afford to lose at first!
