In as much Bitcoin got up to $73000 middle March this year is never certain and guarantee that we are going to see Bitcoin hitting $100k this year which is just two months left to go even though anything can be possible but for a valued coin like Bitcoin making such a drastic upward trend within such a short period of time this year might not really be possible, perhaps we shouldn't be in a hurry to forget that Bitcoin is less volatility even though Bitcoin will definitely hit $100k some day, all that we can only be doing is making predictions and speculations which suits Bitcoin as a valued digital asset class.
You said well, and from this we can also assume that if BTC reaches $100K, or BTC will reach $100K; The question is when!! 2019? 2020? 2021? From this we can predict that between now and 2025 BTC will hit that level and stay above it; But, that is very conservative at this point. And on that day I will be a very happy hodlar.
