You are right, as soon as more people start to adopt bitcoin the demand of bitcoin will increase and with that the price of bitcoin will also increase and with that more people will invest their money in there so it has a more brighter future.
And for that we do not have to wait but we have to struggle hard to invite others to join bitcoin, we have to take start from our home and have to invite our family members and then have to invite our friends and other relatives to adopt bitcoin and then advice them to invite others also, with that only we can increase the community of bitcoin. waiting alone is just useless.
