in present time the best option is bitcoin because the price of bitcoin is going to increase so much, it is also expecting that the price of bitcoin will make new all time high price record in next few moths,
You are being way too optimistic with saying that the price will reach a new all time high in a matter of months.
I don't think we will even see a new all time high in the entire year of 2017 as it comes way too soon.
I prefer the price to build up decent support levels so that when we reach $800>$900>$1000, that it will be a sustainable growth.
