We should also have a post discussing the downsides of different Cryptocurrencies

I always saw a that lot of posts and comments on the this sub have like a one-sided view of their crypto without any mention of downsides of them. I think we focus too much on the good side but we should not forget that the whole cryptocurrency market is still in development phase and no coin is perfect. Each coin has its own downsides and we should talk about that more often so we can improve.

Don't hate on me, I'm a very big fan of cryptocurrencies but I think discussing about the problems and the potential solutions can help us improve them more.

I'll start myself with the coin that I use often and I think is talked quite often in this sub. So yeah you guessed it correctly it's Nano.

Some of the downsides of Nano which I can think of are below and if you have any other valid points, I can add that to this list.

These are some of the problems and downsides of Nano with the potential solutions:

• Marketing & adoption - This is completely true, but sadly goes for crypto in general. Networks always need to start somewhere, and Nano's network effect so far is low. With the amount of enthusiasts it has, this will hopefully change in the future, and because adoption so far is low, so is the price. Nano developers have decided to focus on development and not spend money on marketing, they rely on enthusiasts to do so.
• Privacy - Unlike Monero, Nano doesn't have full privacy. There are solutions such as Camonano, and because Nano is instant and feeless it is relatively easy to send around enough to confuse the trail, but it's no 100% privacy.
• No smart contracts - Unlike Eth, Algo, and Ada, Nano doesn't do smart contracts on the first layer, and makes no attempt to support these. The reason for this is that Nano is built to be as lightweight and fast as possible, implementing support for smart contracts would slow down its function as a pure currency. It's a design choice, in essence.
• Spam - It’s easy to spam the network as it’s fee-less. Current updates don’t eliminate spam attacks, they instead aim to make particular buckets unaffected by it. Yet, we are still to see how effective this is in action. Actual spam mitigation is yet to be implemented. Nano is extremely powerful, but one spam attack could instantly bring it to its knees.
• Decentralization - Nano is currently not as decentralized as it could be. Majority of the voting weight is held by Binance. Users must choose representatives, and users don't always choose the best ones (or never choose).
• Node incentives - There are no transaction fees, so why would people run nodes to keep the network running. Only Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
• Price stability - Why would anyone accept or spend Nano if the price fluctuates so much? Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
• Deflation - Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?

You can comment down below about your coin's problems and downsides. It'll help the community to understand them better like what are the problems associated with a particular coin and it will help them in taking their investment decisions.

PS - Shill me your coins but with their downsides
