Buying at 1000+ and investing is not a good idea. If it falls and you have some extra amount then you can invest and hold it. Ideally it will give you return.
This is not the right time to buy bitcoins I guess as price is pretty high at a moment but if it falls in coming days and goes below $900 or so then it would be the perfect time to buy bitcoins and hold it for next few months in order to make some good profits as price is expected to go higher in coming months.
yeah there is many people says that its not a good time to buy bitcoin and they waiting that price of bitcoin will be fall in few days but i do not think that bitcoin will be fall and it will be much more profitable for you if you buy bitcoin with current price because bitcoin will reach its price to $1500 in few months.
i agree with you bitcoin will be never fall its price and you are right that bitcoin price will be rise to $1500 in coming few months so it really good time to buy bitcoin and then hold it for long time and i am sure you will be make a good profit in the future.
