[st started investing in bitcoin and you're beginning to have a double mind, remember that bitcoin was not launched at $100k. It has been below $0.1 also. So it's not right to think that it has gotten to its peak already.
Anyone that has double mind on bitcoin if it's a good investment to throw some value into should start by investing little amount of money like $10 and above into bitcoin every week and keep his DCA ongoing with consistency and persistency overtime. As he starts buying weekly, he will begin to understand bitcoin as he buys every week through experience. As he is learning and accumulating, his confidence will begin to increase in bitcoin because he will understand that bitcoin price recovers every dip and increases in value overtime.
When he has gotten good confidence in bitcoin and he has cleared all his doubt, he can increase his DCA amount in order for him to buy aggressively to cover up those periods that he was buying with little amount after 1-2 years of his bitcoin investment. Experience is the best teacher. It's better to start with very little amount of money than not to invest at all because of doubts on bitcoin performance.
What if bitcoin falls to $1 today, will you still accumulate??
It's not possible for bitcoin to dip to a dollar because the odd of bitcoin price moving uptrend is higher than downtrend. Give realistic figures.
