I do not like the idea, because one of the main principles behind and forming the base for BTC is the decentralization where there is no central authority or a financial base, and a bank is the base of centralization and just giving your bitcoins to someone to hold it is meaningless, since you can hold them yourself in a secure way.

keeping them in a USB-based smart wallet made from one of the hardware wallet operators, it was just 27 Euros and is relatively easy to use and feeling safer to use it than an online computer.

Bitcoin IS a high risk investment particularly for those intending to hold as short term, the price can (and did, multiple times before) lose 25% or more of the invested USD value in a single day, The price eventually recovered and now is the highest value in these days, but it is still a risky investment, which is why you should be prepared before making a big bitcoin investment.

I guess Nadal's odds of winning aren't too shaddy, with Djokovic having a difficult game and doesn't look that much in shape (even with the comeback), Murray is never stable and can easily get out of the tournament, Nadal and other young player's odds are as good as they may be.
