No, I do not think that it is too late to buy bitcoin. Bitcoin is still an evolving currency and there will be many price increases for the future years to come. More and more people will be looking at getting into using bitcoin and this will drastically bump up the price, even though it has already increased drastically in the past few months.
i also do not think that it is still too late to buy bitcoin. i think is is the best time to do so. because i am sure that very soon bitcoin price is expected to increase too much therefore i think we should not lose the present opportunity and should buy purchase bitcoin.
