I saw something online and it was a statement by From Michael Saylor, i never believed he once had doubt on bitcoin. This is the statement.
Doubt is a normal human reaction to something that is unclear. It's important to dispel doubts: examine the "subject" of doubt, weigh the pros and cons, and make a final decision on whether you should engage with the "subject" of doubt (in the context of this discussion with bitcoin).
This same person that was having doubt on bitcoin is still the same person that now own a firm Strategy that accumulated and holding 671,268 BTC, setting records among public companies.
Michael Saylor is now one of the people that is advocating for bitcoin and promoting it.
If you are still doubting you are alone and those forming a team with you when it comes to doubting bitcoin some of them may even be accumulating and holding bitcoin consistently.

Well, Michael Saylor overcame and conquered his doubts, making him one of the largest holders of bitcoin (and a wealthy one at that).
Since 2013, much has changed in the crypto industry, and bitcoin's position in the financial world has significantly strengthened. While there were many doubts in the early years, these doubts should no longer remain under the "pressure of compelling arguments" – bitcoin has been around for over fifteen years, its value has exceeded $120,000, and institutional investors (and even some countries) are accumulating this asset.
