Alot of people fail to realize that they don't need to buy 1 bitcoin to start their bitcoin investment, the price for 1btc is so high for alot of people that it just scares them away, if they only knew that they can buy their money's worth of bitcoin, and overtime, it will accumulate to an outstanding value that will make all their initial doubts and fears fly into the wind like ash.
Bitcoin investment is simply one step at a time, no rush, just gradual increase until you get to your target amount.
I totally agree with you, nowadays people think before they invest they must first have 1 BTC which is totally wrong, in fact you must not even have half of Bitcoin before they can start. However, I disagree with you on the point that the price of 1 Bitcoin is so high because Bitcoin is still at it earliest stage which means that Bitcoin is still growing and it also means that the value of Bitcoin now is still very small compare to what we will see in the future so you don't judge the value of something that is still growing at that particular instant especially not Bitcoin that has a very high potential that is why anyone who is investing should take it serious and shouldn't stop on the road because anyone who accumulate and hold for a long period of time will definitely smile.
You have already said that it is not compulsory that we must start by buying a whole bitcoin which is right but saying that the price of 1 bitcoin is not high sounds like you are trying to confuse yourself because let us be frank, 1 BTC is about $83,000, can you afford the money to buy it at a go? NO, which means the price is high but since it does not necessarily mean that we must buy a whole bitcoin, but by steadily buying some fractions of it consistently, we can even own more than 1 bitcoin in our portfolio when we accumulate and hodl for a long time. Yeah, i prefer you say that bitcoin is still in early stage of adoption instead of saying that it is still growing though your statement is not wrong but looking at the price of bitcoin when it was introduced and now, you will see that it has really gotten significant growth over the years.
