A lot of factors prevented me from investing as at that time and I don't believe that there is a wrong time to invest except possibly when the price reaches above $50,000.
the price of late are dropping are again at the close of the year 2018 and this is causing panic amongst investors and possible future investors critics has even predicted the drop trend to go on for a while and bitcoin will not recover soon.
But I see this situation as an opportunity to purchase extra bitcoin. Business is all about calculated risk you don't just move with news alone the could be sponsored shilling or FUD bitcoin is over nine years now and has created a good level of establishment.
If you had missed out on bitcoin previously it's fine. If you miss out now then blame yourself
I think that your analysis is pretty much spot on.
Prices are extremely low in the BTC markets at the moment, yet it seems like that institutional interest is not waning. As a result, I believe that there is a real long term accumulation opportunity, if you do believe in bitcoin's adoption going up in the future which I believe is highly likely.
It's however completely possible, if not likely that prices in the short term continues to dip and drop below support levels, as investor sentiment right now is still negative overall. If you do decide to accumulate right now, make sure that you are able to be comfortably be holding BTC for at least another few years. Don't view this as short term gains, but rather an entry point that is sufficiently low in the long term scheme of things that it is worth buying up on.
