BTC is risky, yes. You feel it is too late to take a position, but I think there are methods to still do so. Those methods are called alternate cryptocurrencies. Find one that trades in Bitcoin and buy in on a down swing. It's riskier and with all "investments" there are no guarantees of future success, but let me tell you there are multiple examples of huge price fluctuations and the trading volume to really open your eyes.
Another important thing to keep in mind with cryptosporidium that trade in BTC is that for the most part, when the $ value of BTC increases the BTC value of alternate cryptic decreases. This is another indicator that can help you decide points to buy in.
Many of these alternate cryptos are fairly stable while others seem to pop up overnight and then disappear.
For some real intriguing charts, checkout coins created and named after current world leaders (PUTIN and TRUMP)...
