Need help

Ive been here just maybe 2 weeks.Whats your opinion of someone who has not much money but buys 20 different coins ? Is it just stupid? Should you start eliminating and cut it down ? Im so lost atm would like some opinions. Ta. I put roughly 1/5 in btc. The rest went to a whole load of coins. Currently im in a profit but I fear It may not last as ive heard so many stories of people going in a loss.
