All forms of investment will definitely be at risk, as you experienced in the past, but unfortunately you stop and just want to continue again.
maybe your $ 1K capital, you can invest in new altcoins that may already have a market, but again need deep observation and patience, no need to panic too fast when prices go down, wait and always pay attention to the developments you invest, because the market will always grow, that is the belief you must have.
I think instead of investing in new coin better to invest in some promising and well trusted coin, It is good time to invest your 1000 dollar because coins according to me are at good and affordably coin now a day is bitcoin and ETH, so it is time to take wise decision and buy only bitcoin it has good potential I am sure it will make your money get higher in timely manner, just buy and hold.
