there is no safe place besides investing in BTC or other altcoin such as ETH, EOS & BNB. because they are all promising investments in the future, besides that I personally don't like high risk so I prefer to take part in the top crypto and wait for market conditions to fully recover.
there is no safe place period. there are promising projects - yes, there are relatively stable coins like usdt (but it is tied up with usd obviously).
however there are places aside crypto where you can save your funds in order not to lose much of value (like fonds/bonds)
