The same idea I have before when I wasn't fully convinced to put my time in Bitcoin and cryptocurrency, that is Bitcoin has a limited supply of 21 million. Over time, I understood that the scarcity of Bitcoin's supply is what makes it profitable and could induce more mass adoption. In the first place, you don't need to acquire an exact amount of 1 BTC and above to consider yourself a bitcoin user. That is why we have many denominations for Bitcoin. There we have satoshi which allows us to count faster. Refer to this image:
The scarcity of Bitcoin is what makes it possible for people to race up to acquire the largest amount of Bitcoin they could, as they know that in the future, acquiring 1 BTC will be so hard but it doesn't take the opportunity for them to be restricted in using BTC.
What about the transaction fees?
The upgrade of Bitcoin to Segwit when you are using a ledger nano, or try to look in a block explorer, states that we can save more transaction fees with Segwit. This means that the Bitcoin network can still be improved to decrease the fees and make it more convenient for us to use Bitcoin in the future.
