I think that this is a bad idea. This is a high-risk investment, which can become 0 (unlikely, but possible). It is necessary to invest as much as it is not a pity to lose. 
Well it is true but risk is there is every business so if you will not take risk will not earn profit. Just go for it and will see how it goes, not all people suffer lose in bitcoin. Some of people who invested in bitcoin are now millionaires and they are having hue bangles today just because of bitcoin. Best thing about bitcoin is that it will not let your money get vanish infect it will appear as more than double of your invested amount.
