I agree, some of these investments you listed are very interesting for me, but I don't have enough money to invest on them.  
(And some others aren't very profitable...)

With Bitcoin it's different, I don't need a large sum of money to invest. If I have only $100, it's already enough to buy some satoshis to hold and the profitability is higher than those safe investments you listed with a relative low risk if we compare the proportion between risk and profit.

Bitcoin made investment a concrete option even for that person with low budget, that is amazing.

Are you serious with your answer? looks like you don't appreciate technology? try do some deep research!

About the topic! Why bitcoin and Cryptocurrencies?

Well i'm not into any banks here but if i decided where i'm gonna put my investments well first i will invest in cryptos and bitcoin. Second option is  Real Estate and third Restaurant business which i believe people love to eat so much.

1 Bitcoin = $11,500

1 ounce Silver = $18/ounce.

The 7 investments you mentioned are investment controlled by regulations and government. I rather go with crypto.

Cryptos are needed  to get away from Govt. controlled fiat currencies.Its just simple exchange process of Cryptocurrency.

Yesss but why would I? Cryptocurrencies give us a new and different perspective, it keep us away from traditional investment understanding. I guess this is the reason why young people prefers crypto. Thanks to blockchain and cryptocurrency, a new dimension in economic sense has emerged...  even if I invest in a land or a property, I’d invest in crypto too with the rest of my money

The answer is volatility. Thanks to it, those who know how to trade in the market can earn good money on crypto-currencies. And of course, the multiple growths of bitcoin over the past year has done its work.

There are really a lot of trusted investment that can be chosen instead of taking risk with crypto currencies but why many are now considering it especially bitcoin?... As to me the reason why is because only in bitcoin you can start earning without any start up capital yet in due time you earn so much, it has also the highest rate of return on investment and even if too risky bitcoin has proven that making an effort to take a risk and be patience you can receive so much earnings and can actually change your life to be better.

Thr fact that you included starting a business or investing in one of the businesses you listed as a legitimate safe investment makes me believe you don't know what you're talking about and just threw on an additional portion of your own on some kind of list you pulled from online. Starting a business is incredibly risky, especially when you consider that a majority of the businesses that are started fail within their first year - in fact, an overwhelming majority of small businesses fail within their first few years of running. Not to mention it also requires a lot of time from the owner initially, which takes away from their income from other jobs, among other things. I know some people who are starting their own businesses and they are not safe investments. They're assets or they're hedging against some bad news that could spawn from their current employment.

But at the same time you're a newbie so I don't really care.

I think that the main thing about cryptocurrencies is that it has some significant advantages in comparison with regular fiat.
Anonymity, wide distribution and decentralization are key drivers for people to use blockchain and crypto
BUT, it's still has disadvantages which discourage people. Like long delay between transactions
