It's his strategy, it's his decision. Nothing to advise. If he thinks he'll be successful, then he should follow his world of the stock market and the risks. There is no ideology in Bitcoin, there are ideas, each one with his own. If he takes risks and wins and also has fun, well, good. If he does badly, well, he has the experience. If he leaves some Bitcoin coins behind in the race, I will try to buy them as soon as possible. The next bear market may be, there is still a lot of fluctuation left, if he manages to accumulate more BTC in his stash, then congratulations.
