Stellar has always been a strong investment in my opinion. However, I feel like it may be a bit too early for them still. They released a lot of amazing news last year which drove the price up high, but the news came out way too early and eventually this lead to people selling, driving the price down. Unfortunately it may still take a lot of time since any big named investors will most likely start with Bitcoin and Ethereum, since these two are the most known and accepted. It may take them some time to get into Stellar, which can again cause people to lose faith in the coin and begin dumping their bags.
