I'd never purchase vouchers for the gold/silver I buy unless it was physically impossible for me to store it in a safe manner anymore. I don't know why you would want to buy and store anything on any site like Bitreserve right now. Sell your Bitcoin and buy physical gold and if you're going to buy gold vouchers do it at an established business. The odds of you losing your Bitcoin are mathematically pretty high given there should be a 0% chance in the first place.
I agree with you that if you don't have it in your hand, you don't own it, but for trading pursposes paper gold and silver are much much easier.I had physical (lost it in a boating accident unfortunately) but when the price peaks, it is difficult to sell at a decent price without resorting to eBay, that will steal 10%, or untrusted buyers offline.
If you are trading, paper gold would be fine, for a long term investment physical is the only way to go.
Yeah paper gold would definitely be more useful if you are looking to quick trading instead of a long term investment, but definitely not from a site like Bitreserve. There's to high of a chance that the site won't be able to fulfill the entirety of the voucher. Especially when you are getting into the amounts such as 50 BTC, if something goes wrong with their site as we've seen countless times before with other sites the odds of getting your Bitcoin back are very low.
