My answer to the principle is: NO
Bitcoin is money, the value of money is built on confidence, tradition and security, attributes that Bitcoin offers easily. The analogy between Bitcoin and social networks is completely incorrect, people think that Bitcoin is an myspace that will be replaced by facebook. It turns out that Bitcoin is money and not a social network, so this comparison is completely wrong.
Most of mankind's wealth resides in vaults for hundreds of years, so the circulating medium is derisory close to it. Why are we going to need fast, no-fee coins if we can use paper money and banks? Bitcoin's purpose is to be a safe asset, scarce and superior to gold. What is behind Bitcoin is the fact that no politician can steal you through taxes or inflation, there is nothing safer than Blockchain and Bitcoin. So far no technologically superior currency has emerged to Bitcoin to the point of provoking an abyss between technologies and will hardly emerge.
BUY BITCOIN TODAY AND ALWAYS.
Bitcoin is King Kong
Do not mistake this. Bitcoin (BTC) is still standard of measurement against ALL other altcoins in the crypto world. And when BTC runs or when BTC dips, alts bleed. This is because BTC still rules them all.
And while I have answered questions regarding other coins in the past, I have only focused on altcoins with solid dev teams behind the coin and have the markings of a solid project. However, I never mistake those coins as better than BTC or long term holds.
For example, Ripple (XRP) has a solid run. Many people began buying into it as it started to run and at the all time high (ATH). Those who bought ATH, for example, learned a hard lesson. It took a hard dip and correction and many people were hurt (or in the crypto world, the term is they got wrecked). However, if you were like me, I sold my XRP when it hit the ATH and put it into USDT, then jumped in on a BTC dip three days ago when BTC went from $15,000 to $17,400 (it jumped $2,400) and I pulled back to USDT.
While others who bought into Ripple, currently at $2.73 as of writing this, are waiting for the next price jump (to $3.00?), I made 20x as much buying into BTC while they wait for their profits
because BTC is still the king.
