It certainly has the potential to go down, but I am optimistic about it's future because there is a limited quantity of BTC that will ever exist, it is a decentralized system so there is no entity such as a government that can control it, there is a growing demand from companies who now accept is and consumers who want to use it, and there will always be a value to BTC because it's untraceable nature which makes it ideal for shady transactions because even cash can be traced with hard work.
As for other cryptos I would be wary in dealing with any of them. Although I do not know too much about the others ETH seems to be the safest alternative to BTC.
