You dont want to worry about what the price of 1 bitcoin is as of now. You dont have to buy a whole bitcoin. 1 bitcoin is huge. You can buy equivalent of the fiat currency you can afford. As you hold the bitcoins ,over a period of time your bitcoin will appreciate in value and give you a capital gain corresponding to your investment.
I am investing in Bitcoin(30pc) , Ethereum(20pc) , LiteCoin(30pc) and Ripple(20pc). I think these are the best cryptocurrencies to invest in.
Other than this , you can think about golem ,but I have not invested in it as of now.
