We have compared the current Bitcoin 1-day chart with past data(NASDAQ) and found similar patterns. You can use this as a valuable reference for investment.
https://heartbitintro.oopy.io/Although past performance can't guarantee future results, talking about Bitcoin, it's somehow a good reference.
The decision to invest in Bitcoin should depend on how far we understand the risks. One thing is for sure, bitcoin has only one path and that's upward although the question is
"when it will happen". Anyhow, just accumulate as much as we can, if possible compare to think of anything.
Regardless of the reference, if one is solid about their stand about bitcoin, they will just continue to accumulate no matter what.
