Sorry to break the news, but there is absolutely nothing guaranteed about bitcoin. It could drop back down easily, all it would take would be for the huge ASIC miners to sell the BTC they've mined (and stashed) in their efforts to manage the markets and pump the price. Apologies if this is a shock to you.
Indeed, and there's also the mega-whales (Satoshi-dumps) risks and the 51%-attack risk. Even without any of that bitcoin has been behaving like just another pump-and-dump altcoin in the markets this year. The adoption curve looks pathetic if you compare it to the early adoption curves/trends of Facebook, Apple and other new tech launches. Mainstream folks aren't really using bitcoin.
Remember that talk of ETF/Winklevoss $10K per BTC - seems quite far fetched now. All the scams, thefts and now regulation risks have taken a big toll.
