I have a question how will other cryptocurrencies be treated (Lisk and Ethereum for example) ? Automatically shifted to BTC or will they stay in LISK and ETH? I'm asking due to price volatility and if someone invests 1000 LISK how will that be handled at the end what if price is doubled or if it goes down as well as FIAT currencies?

Will everything be converted to BTC at the time of deposit?
