We are heading into a future that we are not prepared. The economy and markets will likely disintegrate much quicker than anything we have experienced before. I believe the Bitcoin-Cryptocurrency market is going to collapse shortly due to what I see as extreme leverage in the system with very little in the way of cash reserves. I hear stories that trading in and out of cryptos isn’t a problem until you want to receive a substantial amount of funds in your bank. That is a huge RED FLAG.
