Even if Lisk network is unreliable it alone won't change its price in a negative way. Check Ethereum reddit, every day 2-3 new posts about not syncing blockchain appear but ETH price only grows.
I think there is really something wrong with ETH blockchain, its hard to download the entire blockchain without losing peers from time to time. Then you need to restart the client all over again.
More likely it's your connection or lacking IT skills. Downloaded it a number of times for a number of clients no problem. So quit fudding.
