I usually prefer bitcoins trading with altcoin in exchange market. Some of the exchanger sites gives you best insight of what market will be like I'm coming future. I usually buy bitcoins at low prices and then only go for altcoin exchanges. This gives me bigger windows of profits firstly by buying at low price (that's from reducing/covering fees) and secondly going higher on the charts i can buy more amount of altcoin. Well over all this is my strategy and this is what works with others too. Hence people are more into trading and investment of bitcoins.
I ususally keep most of my trading assets in BTC and I denominate my trading account in BTC as well. It makes it simpler to quickly exchange BTC to other altcoins rather than having to go through the bank all the time since blockchain transactions are always quicker than banks. What I would do is to wait until a drawback in btc price, buy up a bunch of btc and then use that btc to fund your trading.
Investing in bitcoin is a good choice. Is not there a saying about economy, which has many taps will be better. Bitcoin continues to be popular with the current exchange rate rise also can be a mainstay of our better future.
