Good coins right now where a very good tech is promising:
Avalanche: Avalanche is completely different from existing projects and experts have given Avalanche a high chance to be a big game changer for Blockchain and mainstream adoption because of interoperability, great decentralization and scalability in addition to low transaction fees. Avalanche is a platform project and when it was reviewed by several experts, it has always become a very good rating. Avalanche has found out how to make consensus more decentralized by using random subsampling where it's possible to scale unlimited because validation nodes participate in Avalanche consensus. For Blockchain, it's after Bitcoin a huge achievement, Avalanche did it and it works.

And because it is developed by Cornell University professors, it has a very scientific approvement and reputation.
IOTA: IOTA has been a leading project for innovative approaches but IOTA developers had difficulties to deliever. Currently, IOTA is very undervalued and can be a very wise pick because IOTA has made huge developments recently, like IOTA Chrysalis (IOTA 1.5).
IOTA project has very big plans. It needs to be mentioned here for development about IOTA: Devs are planning IOTA 2.0, it will be like Ethereum 2.0 but for IOTA. Not many people know it but when Ethereum 2.0 will be huge, people will also know about IOTA 2.0 and buy huge IOTA. Price can go up a lot.
It has several phases for IOTA 2.0 like for Ethereum 2.0.
Phases of IOTA 2.0 are Pollen, Nectar and Honey:

Sushiswap: Sushiswap is a famous decentralized exchange where people can very simple do a swap. It is like Uniswap but different.
For fundamentals, Sushiswap has more swaps per day but in price, it is way below Uniswap. Uniswap and Sushiswap are competitors and Sushiswap is currently very undervalued against Uniswap.
For Sushi, it is also important to know because many people will like to eat sushi and will decide for it. It is like many people like Doge.
I trust all coins to make a good profit.
