At 52, I didn't have enough money to invest in my private pension previously due to raising a family as a single parent. I have 4k savings and I'm wondering what the best way to invest? Whether to pay all this into my private pension (Scottish Widows, not a great return on the basic rate I'm paying) or to put it in a savings account like Chase or something similar. I'm very wary of other types of investment schemes, like Bitcoin whatever...
What are my options?
