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.
Bitcoin can reach 40 thousand if we speak about 4 years. In 2019, it can reach 15 thousand. Now, BTC can fall and roll back to 10-9 K, but it will be a temporary correction. next, in July (late July), BTC will start next Moonrise.
