Do you think these coins will stay in the Top 10, or like dozens of other altcoins end up being overtaken by others?
With the performance of these two coins, I think both has what it takes to remain at the top ten coin on CMC ranking, and may move further in near future. I think top 3 coins on CMC ranking may be the only Strong projects that may resist the potentials and a possible overtake by both polkadot and chainlink fast growth.
These coins has proven the fact that it is really difficult to predict crypto, and that anything can happen. Many more unknown coin/tokens may also spring up surprises in near future. Crypto is full surprises, let watch out for more smart projects that may put up a good performance other than polkadot and chainlink tokens.
It sounds ambitious to think this, but fair enough. I always assumed that while they both would remain very successful projects, staying in the Top 10 isn't exactly a barometer for being useful and valuable. It seems every year there are new projects that enter Top 10 that never stay there long. The only exception to this rule would be that we *appear* to be starting a new bull market, so in an altseason these two projects could hold their ground against any other newcomers, but I'm also not sure it really works like this, despite LINK's incredible rise to the Top 10 that looks like it might have some staying power.
I still remember the amount of coins that used to be Top 10 even relatively recently; Stellar, EOS, TRON, Monero, NEM, Tezos, basically half of the coins ranked 11-20! I guess this is where my pessimism comes from, seeing so many projects get overtaken by the latest flavor of the week, month or year. As you said, the exception to this appears to Bitcoin, Ethereum and XRP. No other projects have survived the test of time, apart from Litecoin I guess.
