The previous fixed investment BTC plan, 'BTC for Children', was 300U per day for 18 years and has been fixed for a month now. The current average price is $105738, with a total investment of $9270, ROI 1.57%， Can it also be indirectly explained that BTC has been oscillating around 105K in the past month, with little room for growth. Looking forward to BTC's ROI performance in 18 years~
