Of course it is possible, you don't have to use "TDAmeritrade.com" to manage your investments. You can hold the contract paper yourself if you like. A broker will charge more for those type of direct holdings when a trade is made however. Which is why it is popular to use the retail brokers that manage the contract for you.
My point was, there is really no "use" for a stock holding aside from the obvious as an investment. So simply investing in and holding a stock is fine.
The popular Crypto coins are supposed to have other uses, like a cash replacement. In fact cash replacement was intended to be the primary use for Bitcoin. But most people treat them as an investment they can just sit on and watch go up, like a stock.
