I heard Ethereums popularity causes its network to become overloaded, which raises how much it costs to run ICO’s?
Any advice greatly appreciated as there is not much information on Google.
Thanks
First of all ask yourself what are you trying to achieve with your project? What it is all about? If you are trying to do some smart contracts and dApp thing ethereum might be the good solution because of their huge database of users and because it is well known so you should be able to get publicity faster, although it all depends on your marketing strategy at end. For instance on Waves it is much easier to create your tokens with GUI where as with ethereum you will have to know programming a bit. Stellar might be good choice because of it's fast network and low fees, ethereum fees are like 1$ now.
