I can not disagree with what you're saying because from your point of view it is true, but not everyone's the same. Not everyone prefers one single type of action towards Bitcoin and let me explain you my point of view.

So as I though about obtaining a BTC, i considered 3 types of action:

1) Trading - to buy btc or altcoin and sell it when it's on it's highest and buy it when it's on its' lowest! That is not for me, I do not have that much time, i do not have that much education and I can not predict the price changes of a financial instrument, so scratch that!
2) Hodl - of course this is the easiest way to obtain and keep a btc. it's a non risky way (i mean the whole risk is on your shoulders if the price goes down) so if I buy $1000 of BTC and i hold on it for a while, I can either just gain some income if the price goes up and, or either lose some money if the price goes down. I will still have that 0.13 BTC (with today's price) but that will be all - nothing more, I will just have 0.13 btc and it won't grow or something.
3) mining - now here you will say that if I have money i should buy my own mining equipment and mine btc myself, but my arguments stay - it is way easier and better for me to mine btc via cloud mining services, than to buy equipment i have no idea how to take care of, where to buy, what kind to buy, how much to pay for, what to do if it breaks, etc. I don't have a place to place a miner and i have heard sounds that it produces, i can not bare that! So.. i preferred cloud mining! Mining is the best choice for me, because if I buy a $1000 of hashrates (instead of buying a fixed 0.13 BTC) i will have income in btc. And if you'll say that my potential 0.13 btc will grow as well with the price growth, i will say that from mining my everyday income will also grow.

I don't know if I formulated my thoughts correctly or clearly, but all this is why I chose to cloud mine btc. Even though I had a lot of bad experience with different companies, i wouldn't say they were damaging or I had a big loss, i still prefer cloud mining even after these experience. I just found a company which suits me the most and at least takes care of me.
