For 123 days from 20210115 to 20210517 using BTC-USD data from yahoo finance, I created ten genetically-optimized functions to model the close prices (I think the input price times were just before midnight in London). Code: y = 27129.16015625 + 776.614135742188 * x - 4.87528514862061 * x * x + 3878.65161132812 * cos(twopi / 27.8717126808746 * x + 5.75866985321045) + 1730.73413085938 * cos(twopi / 18.185257881792 * x + 6.05020952224731) + 1621.51672363281 * cos(twopi / 35.2888819480955 * x + 8.97565041668713e-06) ; y = 26990.6484375 + 780.979431152344 * x - 4.90301942825317 * x * x + 4064.14599609375 * cos(twopi / 28.0650093216463 * x + 5.88462257385254) + 1779.24169921875 * cos(twopi / 34.3248349637699 * x + 5.89317178726196) + 1729.09814453125 * cos(twopi / 18.2185398285009 * x + 6.10203838348389) ; y = 27162.5703125 + 773.541687011719 * x - 4.84463691711426 * x * x + 4028.40966796875 * cos(twopi / 28.042165807071 * x + 5.87620401382446) + 1757.27941894531 * cos(twopi / 34.4031389621893 * x + 5.94523525238037) + 1731.18139648438 * cos(twopi / 18.2309004477771 * x + 6.11719846725464) ; y = 27041.724609375 + 778.580322265625 * x - 4.88352680206299 * x * x + 4086.70654296875 * cos(twopi / 28.0956625809556 * x + 5.9065957069397) + 1803.634765625 * cos(twopi / 34.2371762874817 * x + 5.86289215087891) + 1728.76403808594 * cos(twopi / 18.2298962899221 * x + 6.1174693107605) ; y = 27129.158203125 + 775.021789550781 * x - 4.85641765594482 * x * x + 4023.49389648438 * cos(twopi / 28.0244135607667 * x + 5.86471700668335) + 1739.92980957031 * cos(twopi / 34.3957834902751 * x + 5.93988847732544) + 1731.74096679688 * cos(twopi / 18.22481886869 * x + 6.10759115219116) ; y = 27050.384765625 + 778.505981445312 * x - 4.88413906097412 * x * x + 4036.57763671875 * cos(twopi / 28.0412501546224 * x + 5.86883878707886) + 1752.08178710938 * cos(twopi / 34.4271973959661 * x + 5.94261598587036) + 1729.70886230469 * cos(twopi / 18.2184611120507 * x + 6.10108423233032) ; y = 27028.001953125 + 779.250793457031 * x - 4.88928985595703 * x * x + 4048.39428710938 * cos(twopi / 28.0445512599216 * x + 5.87252330780029) + 1759.69982910156 * cos(twopi / 34.3786544372439 * x + 5.92116832733154) + 1729.31579589844 * cos(twopi / 18.2193994564096 * x + 6.10035133361816) ; y = 26956.435546875 + 782.3525390625 * x - 4.91309309005737 * x * x + 4061.8486328125 * cos(twopi / 28.056772110517 * x + 5.87940263748169) + 1778.49291992188 * cos(twopi / 34.3481935780325 * x + 5.90047836303711) + 1728.22277832031 * cos(twopi / 18.2173859134461 * x + 6.09882164001465) ; y = 26939.439453125 + 783.068359375 * x - 4.91849279403687 * x * x + 4070.68774414062 * cos(twopi / 28.0705078436473 * x + 5.88754749298096) + 1784.20251464844 * cos(twopi / 34.3121037336195 * x + 5.88407850265503) + 1729.36328125 * cos(twopi / 18.2137598251196 * x + 6.09636640548706) ; y = 27179.302734375 + 774.473815917969 * x - 4.85865068435669 * x * x + 3875.80126953125 * cos(twopi / 27.8732511118077 * x + 5.7613000869751) + 1731.06884765625 * cos(twopi / 18.189547415724 * x + 6.05675745010376) + 1623.21704101562 * cos(twopi / 35.2770518112427 * x + 6.83088728692383e-06) ; y is the modeled priced of BTC-USD. x is the number of days since the beginning of the input data. twopi is 6.28318530717959. cos is the cosine function which takes an argument in radians. The input prices (+ signs) and the ten functions (curves) extrapolated for 21 days are: They predict the next turning point on about 20210528.
I think the Tesla buy into BTC was around 38K, so currently under 33K they are heavily under water. I can't believe they were not smart enough to sell over 50K, specially when he knew he was going to embrace Doge. Although I wouldn't be surprised if the next quarter's numbers show they did cash out at a profit.
