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.
Investing in one coin is like putting all egg in one basket, i do some calculation to balance my portfolio such that if one coin goes down, the others can compliment it, that's my winning strategy. i see bitcoin going beyond $10,000 this is my honest expectation right now, it has been a good ride from $3,900 down to $9k plus
