I don't think the cryptocurrency market is sinking,
I've been involved in cryptocurrency for about three years,
I can tell from my personal experience that the cryptocurrency market will never sink.
On the contrary, the future of cryptocurrency is very bright in my opinion.
But we are talking at the moment and the chart is showing signs of an upcoming bear herd. Do not be too subjective about the price of Bitcoin as all altcoins will continue to increase in the future. Looking back at 2017, everyone was as subjective as you were and in the end its price dropped from $ 19k5 to $ 3k5 in just a few weeks.
In the crypto market, anything can happen and it is best to have a backup plan when the market starts to collapse. This is a very sensitive time and I recommend you to prepare plan B, the subjectivity is easy to make us fail in trading.
