I went through a somehow similar experience this week when I lost almost 100$ from my wirex account right after a sudden increase by almost 20% of BTC, followed by a decrease of 18%. When I saw the percentage rising, I rushed to buy more BTC, LTC and ETH, the 3 cryptocurrencies I'm currently investing in. I was hoping for a further increase, but the next day all the cryptocurrencies were down by a significant percentage so my investment was not worth it. Now I am waiting for the numbers to rise again.
