I'm a bit busy for surveys presently. Nevertheless, I'll give you my views on why Bitcoin is preferred by most crypto enthusiasts.
Pioneer Crypto: Bitcoin is the very first crypto currency and wherever you talk of digital money, it gets mentioned first. The first and the best. That's the thing with being first
2. Antecedence: Bitcoin has come a long way. Experienced a lot of vicissitudes and is still going strong, so people believe and trust it not to disappoint and it hasn't for those who stuck with it.
3. Value: The crypto has value however you look at it. Irrespective of what the governments are saying, Bitcoin has value. That value is based on user perception. A lot of people may not believe in its sustainability but even they cannot doubt its value.
4. Even Skeptics Take Note: Folks that berate it as a bubble can't help giving due regard to its survivalist trait. Ask that JP Morgan guy. Many skeptics are now even purchasing Bitcoin. Who wants to miss out on it?
5.Band Wagon Effect: That the coin has survives a lot is not in doubt. Hacker proof, forks and what have you. It made a name for itself and people have taken note. When new folks want to invest in crypto, Bitcoin is currency of choice.
6. Inflation Proof; You may have heard there are finite number of Bitcoins to be mined and that the mining difficult increases. Bitcoin is very valuable and not like national currencies they mint at will. That's why it has beaten all the national currencies.
7. A Digital Asset; I wouldn't know if you've got some coins yourself. Try getting some coins, I mean Bitcoin, by next year you'd be surprised how much it would be worth. I got my first coins last year but sold them off
bad idea, very bad, so now I'm collecting more.
