Btc, Ltc has lot more real world applications and being the oldest will never lose in the game of being the superior
There are almost 0 ICO's if there isn't a coin like Ethereum as Eth is the fuel which runs almost half of the ICO's based on blockchain. Hence Eth losing it's position is literally a rare case.
I don't believe in the shit coin named BCH. On contrary, why should a hard fork exist on the whole? If you are not happy with(disagree) the block size or the ASIC mining why the hell are you forking btc? Just start your own coin and name it something like MBcoin, GBcoin, TBcoin etc., but not Bitcoin XYZ So this should have a huge fall and should run out of the Top 10 if crypto is in it's winter season.
There has been claims and accusations on Tron being a Scam or being over hyped. I don't think this will continue in long run.
Monero seems to be a very promising coin based on the cryptonote technology and being completely anonymous. Stealth address has failed to compete with segwits in btc blockchain but there usage on Monero seeems to be really good. Some other notable coins are Dash, NEM and Neo. I can't really comment on Xrp,Eos, Cardano,Stellar as I have never read about their underlying technology.
If there is a crypto winter populated by bears, possible top 10's may include Btc,Eth,Ltc,Monero,Neo,Dash,Xrp(not sure)
