yes it is all according to the budget we have, if I only have 1 BTC to invest I will choose coins with a cheap price value like TRX or DOGE, chances are I will have a large amount, when the price goes up a little it will benefit me
maybe dogecoin is better for investment. I myself prefer and make it my favorite asset that I always have. investing 1 btc for dogecoin might be a good choice, or you can share it to buy partial trx.
