I'm sorry, but i have to disagree with most of your tips... The following answers are reflecting my personal opinion.
The fastest way to increase your bitcoin is through gambling. Its unstable but if your an expert to it youll be rich overnight.
I'm not sure if you can become an expert in gambling... There are odds, there is a house edge. If you're lucky, you can make money (even get rich overnight), if you're unlucky you'll lose everything. It's statistics pure and simple. Some strategies might look great, but in the end, it's all averages, odds and edges, and the house always wins. The exeption might be skill based games. If you're an expert poker player in a room filled with newbies, you might have a big chance to gome home with a lot of coins.
The second is investing on onpal and hyip. You must be an early bird to catch early bitcoins later on it will collapse and nothing will be left of you.
I would never ever suggest anyone to invest in a HYIP. They're basically scams.
The third is investing on mining, make sure to select mining site that are on business 3 or more years already.. small income but harvest it 5 years from now. instant millionaire haha
If you're talking about cloudmining: there are only a handfull cloudmining companies that are legit. The rest are ponzi's... If you're talking about homemining: the golden years seem to be over. With a good business plan, good calculations and a good power price, there might still be money to be made, but it's certainly not for anybody that doesn't know what he/she is doing
Fourth is hoarding, just let your btc sleep in your wallet it will go up in time as btc rise up in value theres no stopping it.
You are correct... It's a gut feeling, but i think the same way. In my opinion, it's not a proven fact tough.
Lastly, engage in trading, dont trade overnight but wait every halving of altcoins before exchanging or trading that way your income is at best.
I don't have enough experience trading, so i'm going to take your word for it.
