EOS and OYIR I think it will grow again and this is quite promising.
if you want to invest long term I suggest you invest in BITCOIN, ETH, NEO, and other top coins. because the risk is not too big.
in any case, to try your luck with Bitcoin makes sense. But the main thing is not to invest too much in Bitcoin, so you do not have to lose it later. But in relation to the etherium, I can say that this is a good investment and it is not worth investing in its competitors.
