if you wanted to invest in altcoins then remember in crypto there are too many big potential project and too many scam projects also
So it is important to not rely on anyone
A good invester always divide it's investment as it can afford any scam and loss
So I suggest you to please try to invest in high marketcap coins having strong community like eth xrp bch ltc xlm dgb Nano many more
These names are just for examples not suggestion
There is a lot of risk in low marketcap coins but it doesn't mean low market cap projects are not good project there may be
But do your own research first I prefer

If you searching for the best then remember best things are always at top
Off course if new people wanted to invest in crypto then btc is best and first option as  according to its history it always gives good return in long term investment
At last I reminded you that invest only that much which you can afford because panic selling is common in crypto
But good research by yourself about your investment can remove this problem
