Bitcoin is definitely one of the most lucrative coin you can invest on, I agree with you that it is so beneficial for couples on, so as to generate a much more profit at the end of the investment. It is such a brilliant idea that I would also love to try as well, it is such a bright idea seeing couples going into the same investment, especially Bitcoin among every other coins which are not too rest assured to venture into. Also, understanding the support and resistance point in trading is very important in order to avoid investing on crypto when the market is at the bull point instead of buying when it is at the bear points.
