if you want coins for the long term, I suggest the classic coins can be the solution, like Btc, eth and others.
but if you want for the short and long term, I think an ICO project can help you. because usually coins from ICO can produce a considerable profit with short term (about 3 months). but can also be used for the long term until the true platform of the coin is gliding.
many ICO are ongoing at the moment and we are sometimes confused to choose it. but try to see my signature.
