To me, it seems like it is going to be difficult for you to persuade me that trading is better than strictly buying, and even if you are able to show it in your case, it is going to be difficult to show how you really are going to make your approach to be applicable to others, if it were to be more profitable than a more strict DCA buying approach to accumulating BTC
Bitcoin accumulation with DCAing method is better than trading , I'm speaking base on experience, though trading ain't bad especially for those who are skilled are fully understand the system of trading and stuff. But back then when I was trading , it was really challenging, though I won't say I have much knowledge about it , I will say I was average in it ( half-size knowledge) . But still it was very challenging, making losses and profits , but got to a point my losses started overwhelming my profits.
But when I started bitcoin accumulation, I wasn't even avarage when it comes to the knowledge aspect, I was kinda like a newbie in it with only the basic knowledge, but I was still able to keep up with the pace , investing in bitcoin using DCAing method and I was able to see sone nice results that kept on encouraging me to keep going . Which means that bitcoin investment is open for anyone, aslong you have interest in it , while trading in the other hand might not be for every one , because is not everyone that would have the chance or time to sit down and start learning about trading , because in order for one to be successful in trading one need to take he or her time to gather good knowledge about trading before they are good to go .
Bitcoin has lots of potential, that's agreeable and that's why different people who believe in it speculates different prices, I've seen speculations of 100k before next year, I've also come across speculations of 200k by next year from Crypto new channels on the media but all those are mere speculations and none is right until it happens. However, I still stand on the ground that the 80 to 100k mark in the next bull season is a possibility and more realistic compared to 200k and above. I so much believe in Bitcoin, infact seeing it reach different all time highs in different circles is enough for anyone to believe in it but what I'm not very sure of is your speculations of Bitcoin getting to $1m in 10 to 20 years from now, I find that figure very unrealistic because Bitcoin was created in (2009) which is about 15 years before now and since then, it's not even reach 80k yet not to talk of 100k. If you had said about 500k in the next 10 to 20 years maybe I would've been convinced but then I doubt if Bitcoin would reach the figures you're speculating at that point in time.
There's a reason why is called the first digital assets, yeah bitcoin is feel with nice potential and those who are investing on it are aware of that , though most of this prices listed by you are just speculation, folks still believe bitcoin will surely reach that price range , though we might not know the exact time but there's still chance of bitcoin hitting that range soon .
