AS per my experience of 3-4 years. we can expect 25000-30000$ per btc maximum. what is yours?
But do not invest your all money to btc , only invest what you can afford to loose. Do not put all the eggs to one bucket , diversify it. if you have 100$
50% put to btc others to alt coins.
Of course, you should not invest all your money even though the price is very attractive to invest, you still don't know what's going to happen, invest on what you can afford and comfortable to invest, a lot of good news is happening around Cryptocurrency, the facebook coin the halving the netflix documentary, all of this will contribute to Bitcoin reaching another all-time high.
