It's a good idea to invest in good ICOs. You just need to dig deeper and be vigilant. Choose ICOs that solve existing issues and strive to make it better. Another problem facing the existing blockchains is the cost of a transaction. If you’d like your transaction to be processed faster, you must be willing to pay higher fees too. You should check out NeuronChain, the cost of transactions is way more cheaper as it charges only 1 NER per transaction! Learn more about us here: http://neuronchain.io/
