In my opinion, now is a good time to invest in Bitcoin. Now Bitcoin has a very low price, only about $ 6000. We should buy and hold long-term Bitcoin if we want more money in the future. I believe that by the end of this year the market will be better and Bitcoin will reach over $ 20000. In addition, we can invest in altcoin such as Monero, Cardano, IOTA and Stellar
Investing in BTC is safer than investing in Altcoins. However I think altcoins can give us more profit than BTC. It's really hard for BTC to reach the prices that 5 times compared to now but Altcoins can, even 10 times or can be more
