Yeah could do but I take the view that if I had that amount in cash I would be using it to buy bitcoins. I bought as a long term as a hedge to the “what if” scenario of bitcoins becoming an accepted modern version of gold, only better, and also because I think value will go up much much more.
There are guys who are “trading” buying in and out. I think they are kidding themselves if they think they can time buys and sells successfully. And others who are taking gains in bitcoins and then buying various alt-coins and icos. Not for me. I always planned to buy/hold/stash away.
Having said that, if we do get to 100k per coin by 2022 I would probably sell a coin or two and put the cash into stocks.
