1. Standalone projects that run on own blockchain are better
I can not say your opinion is exactly true. Creating coins with their own blockchain is not easy so the majority choose the easier one. Actually this is an easier option, which saves from a lot difficulty but there are always bad ones. This is a simplified system for us but since it is easy for everyone to do it, these kinds of weaknesses can happen.
2. Projects that doesn't raise any funds through ICO OR IEO are doing great than erc20 projects.
This is true for the few coins that are in front of eye because they can afford their own expenses and they have enough money to prepare the product.
But look for useless coins based on wave, there are hundreds of them, they also do not need ICO or IEO.
3. Ethereum have to reach 1***$ for investors to gain profits from all erc20 tokens
We all know about present dominance in the market. This is a prolonged issue. ETH's reaching $1000 in the current situation means that the BTC also reaches certain level, which means that the entire market increase.
